The Snowblower Wars, Round Three
This isn’t really about snowblowers. It’s about my well-documented propensity for shooting myself in the foot and not learning lessons until I’ve been taught them three times.
Living in the tightly-packed suburbs on 6600 square feet of property, I don’t have a big driveway, so I’ve never needed big snow-moving equipment to clear it in winter. For years I had a Honda HS520 single-stage snowblower. It was an odd-looking little thing that resembled a tortoise with a snorkel on its shell. It was useless if the snow was deeper than ten inches or wet and heavy, and there were limits to how well it could drag itself forward on its rubber snow-throwing paddles, but its 20-inch width was great for blowing out between the cars, and if I needed to bring it over to my mother’s house, my wife and I could lift it into the back of the station wagon.
Initially it was Honda-reliable, which is what you want from a snowblower because pulling them apart curbside in winter really sucks. And like their vaunted lawnmowers, it usually started on one easy pull. But over time, its performance dropped. One issue was that if you pushed it beyond its limits and tried to keep hammering it into deep powdery snow, it would die and wouldn’t restart. I found that the baffle plate over the carb intake would clog up and starve the thing for air, though why this problem seemed to worsen over time was unknown.
But the other issue was my completely self-inflicted wound of not wanting to pay the equivalent of $28/gallon of something like TruFuel ethanol-free long-shelf-life gas specifically made for outdoor power equipment. (Note that, to the best of my knowledge, there is no ethanol-free pump gas available in Massachusetts. The locations that pure-gas.org shows are all either yard equipment stores selling little cans of TruFuel, or race shops selling big expensive cans of Sunoco race fuels, or airports or marinas where you can’t simply drive up in a car and fill a gas tank or a portable container.) Nor did I use fuel stabilizer. My rationale was that I routinely let over-winter storage of my cars creep from three months to more than six, and never once saw an issue with starting or running that I traced to old gas. Now, I’m not an idiot, at least not here—I’ve certainly experienced the gummy horror that can come from cars sitting for years. But for one winter to the next, I just wasn’t seeing it.
Not surprisingly, I was wrong, and old gas caught up with the Honda. In my defense, I think that one winter it didn’t snow enough to use it, so by the time I fired it up, the gas was closer to two years old. By the time its carburetor had gummed up and I pulled it and cleaned it and got one more season out of it, I was ready to move on.
Marketplace
Buy and sell classics with confidence
I bought a vintage MTD (Yard Machines) 24-inch snowblower from a retired guy who had a hobby-business of resurrecting snowblowers and lawn tractors and reselling them. He had a lot of energy behind the whole “They don’t build them like this anymore” thing that resonated with me. I paid more for it than I should have, but I liked him, his little retirement-passion operation, and the idea that this blunderbuss of a snowblower would run forever. And the electric start was great for my aging back.
Unfortunately, it was not my smartest purchase. Like the little Honda, the MTD would die when I used it to clear deep snow and simply refuse to restart, though if its fresh-air intake was packing with snow as the Honda’s was, I never caught it in the act. The seller said that I was working it too hard, and that friction from ice on the impellers was dragging on the engine and causing it to die, but I never saw any direct evidence of that. Several times I needed to either work on it outside in the cold or drag it into the garage and thread it past the vintage cars to work on it, the ultimate thumb-in-the-eye for something that you need to do its job.
Then, in preparation for winter a few years ago, when I pulled the MTD out from under the back porch and tried to fire it up, it wouldn’t start. I found that I’d mistakenly left it full of gas even though I swore I’d drained it. D’oh! I goosed it with starting fluid and it started, then died, the sure sign of a fuel delivery problem. I pulled the carb off, took it apart, blew out the jets and passages, but it made no difference. I mentioned it on Facebook, and a few folks chimed in that Chinese-made carburetors for Tecumseh engines are unbelievably inexpensive on Amazon—like fifteen bucks shipped—and are a quick solution to this problem. So I bought one branded “HOOAI” (like a soldier might say if he was talking about himself) and installed it. Problem solved.
Until last week. A decent-sized snowfall was predicted for Saturday night. I again rolled the MTD out from under the deck and again kicked myself when I found it half-full of fuel from last winter. I ran out and got a few gallons of fresh gas, topped off the tank, again connected the extension cord, again was surprised and disappointed when the electric start did nothing, again goosed it with starting fluid, but this time was thrilled when it stayed running. Okay, I thought—dodged a bullet this year. I put it in gear, self-propelled it up the hill from the back of the house, and staged it at the end of the sidewalk.
That evening, I had a gig in Providence, Rhode Island. I was concerned enough about the snow that I drove the Armada with its awful 13mpg fuel economy. The gig was in a coffeehouse up the hill from the Providence River in an area reminiscent of Beacon Hill in Boston. The narrow little roads leading there were steep enough that I imagined I’d need the four-wheel drive to get out of the curbside parking spot when the gig was over. But to my surprise, I came outside to find no snow. It wasn’t until I got off I-95 that the first flurries reflected in the Armada’s headlights, and by the time I pulled into my driveway, everything was full-on white. I couldn’t have timed it better had I tried.
The next morning, I was greeted with six inches of fluffy powder. Sleet was predicted for later in the day, so I wanted to deal with it before it turned to cement. Right then. I was prepared for this. I fired up the MTD, let it settle into an idle, took one pass of the sidewalk… and it died. It would restart with starting fluid but would only run for a few seconds.
Fuel delivery. Again. Likely clogged carburetor. Again. WHY CAN’T I LEARN THIS LESSON?
My wired-in Hack Mechanic reaction was to grab a few tools and begin pulling the carburetor off, or at least drain the gas out of the float bowl, but it was overridden by my brain telling me “You are getting too old to troubleshoot another snowblower curbside and have fuel soak through your gloves in 20-degree weather. Just shovel the damn driveway and be done with it.” I dragged the dead snowblower back to the end of the sidewalk and grabbed the shovel. Normally my oldest son (who lives with us) does that, but he’d just badly sprained his wrist slipping on ice while walking the dog, so it was just me. The snow was light and fluffy enough that I got things shoveled out without reinjuring my fragile back.
But as I finished, the sun came out and temperatures suddenly became quite comfortable. I looked at the dead MTD snowblower, sighed, and thought “Yeah, okay, what the hell, once more unto the breach.” I grabbed a few tools, pulled off the box covering the carburetor, and dropped the float bowl.
The whole thing was corroded, likely a combination of cheap metal and water that was attracted by the 10 percent ethanol fuel.
I unbent a paperclip and stuffed it up the port on the underside of the carburetor that went up to the needle valve, put the carburetor back together, and tried again, but it didn’t cooperate. Nope, done.
I went back inside the house, searched through my old Amazon orders for “carburetor,” and found the link to the HOOAI carb I’d bought two years ago. The price had increased to $19.
Click.
I went back outside, and in about 10 minutes had the two 11mm nuts securing the carburetor removed. I covered up the intake with aluminum foil to keep it safe from the elements. The replacement carb arrived the next day. I got it installed just as quickly, turned the petcock to let fuel flow in, and the MTD fired up on the first pull.
On the one hand, spending $19 every two years on a disposable replacement carburetor and taking maybe 20 minutes from start to finish installing it is a low price to pay for my own foolishness. On the other hand, $28 for a gallon of TruFuel is starting to look like smarter and smarter money spent. As soon as I run the tank dry, I’m in. I’ve probably got half a gallon of fresh fuel in it. Hey, a buck fifty doesn’t grow on trees, you know.

Had similar experiences here in Soth Africa with petrol powered lawn mowers, brush cutters and chain saw.
I have developed a ritual to start the generator once a month at least.
Sea Foam is the answer. I use an additional ounce over recomendations, Have better luck leaving fuel in the tanks and start the equipment every one or two months and top off the tank. You can buy it by the gallon at a discount store in oh. that gives a 11% rebate on purchases
I run ethanol free in all my yard equipment. No issues. I’ll run regular ethanol in my boat all summer and the last 5 gallon tank of the season before storage is non ethanol Also my daily driver gets ethanol free the last tankful before winter storage. Then the rusty 4×4 beater with a heater gets put in service. Snowmobiles always run ethanol free just because
My 30 year old MTD blower was ALWAYS drained of fuel, carb drained and Stabil poured into gas tank and starter pulled a few times to get Stabil into system. Next winter use fresh hi-test gas and no problemos! Take from me in the Ontario snowbelt in Canada!
I have always had two views on this – blower or no blower? A good part of the year you can drive over it. But this year is different – two 25 inch + lot of 2 inch. I am getting on but still doin with snow slider and shovel. Driveway is about120 ft.
The benefit is that I get some good exercise and avoid the horrors described with cold weather carb.repair. The disbanding is that can cause wife problems
Alcohol also dries out rubber parts such as the o ring some carbs have in their needle valve. All my ICE get ethanol free with stabil in the fall. My chain saws are synthetic fuel only, all the time. I’m glad we voted for the EPA folks to make these laws. Oh wait, we didn’t. Well at least they have the data to prove it’s a good thing. Oh wait, they don’t. (the sarcasm isn’t meant to be political, it’s meant to be factual)
I use Trufuel and have for several years in my Craftsman snow blower with a Briggs motor. No problem ever. I Learned my lesson after lunching a Tecumseh (bad bad) MTD blower. I know Trufuel is expensive but when you have to address a snow emergency, it’s a sure start every time.
I have an MTD very similar to yours and it has been easy to start for for over 30 years. I use non-ethanol gas and at the end of winter I drain the tank and run the engine until it quits. Some maintenance is necessary such as new belts, new spark plug. A few years ago I replaced the friction wheel. I also installed some rubber paddles on the 2nd stage auger that I bought on Amazon. This greatly improved blowing heavy/wet snow and kept the chute clear. Also replaced the 00 grease in the gearbox.
Getting rid of ethanol, which I call mid-western socialism, should be a top priority given all the damage it has caused. This is compounded by the fact it is 20% worse for the “climate” vs. normal gasoline. Living in NV means we don’t have any place to get real gasoline and it comes from wonderful California. Don’t believe me? Look it up on Engineering Explained on YouTube.
Buy “SEAFOAM” gas conditioner and cleaner, and USE IT !!! Works like a charm. I use it in my small equipment and my ’68 Mustang when I take them out of storage. Never heard a shudder or a stutter from them since I started using this product.
i do not use ethanol contaminated fuel in any of my motorcycles or old cars. Never. That stuff is garbage. In northern Ontario a snowblower is an absolute necessity, this year the snow bank in front of my house is as high as the roof on my 2007 Ram truck. The rest of the driveway banks are only 3 1/2 to 4 feet, so not so bad.
My almost 30 year old snowblower has a Tecumseh 8hp motor, which i never start at full throttle. How would you like to go from dead stopped to full throttle at 20 below. I give the old girl a chance to warm up.
We have a new gas chain here in West Michigan, Kum n Go and they sell 90 Octane ethanol gas. I am going to run it in my snowblower and lawnmower
Older units don’t have the rubber compounds to deter ethanol. Not mixing stabilizer correctly is another factor. Look at the cap on the bottle, it gets gummy too so proper dilution in necessary. I only use TruFuel (4 cycle) on the first start up and the last run, filling the tank with a half can. It’s more of a clean out than always running my small engines on this synthetic fuel. Reg gas w/Stabil thru out the season. I left ethanol gas in a seldom used 2 cycle (40:1) weed whacker, it gummed up the tiny hoses and were as squishy as worms and it clogged the barrel filter. It’s really a good idea to set a last day of use for small engine equipment and drain/flush out the tanks before storing, not so much about what fuel to use. A marina 100 miles away I could pick up 5-10 gal of regular e-free gas for a gas/snow seasons but always forget to tote around my jugs.
I would say frequent cleaning or changing air filters and gaskets, also steel tanks without strainers allow crud to build up. As others said, internal engine cleaning products help including use of carb and oil cleaning agents in the fuel. These engine always seem to run dirty no matter what the EPA tag says, maintaining one is annual.
October & May it’s a regular job for me, but I’m retired. I had my 7hp Ariens since I was 25. I’m 71 now. 20 minutes of maintenance twice a year & youshouldnt have any problems.
Just a little advice from someone who had the same issues with his Honda HS 520(and still own after 20+ years), I down know if you do this, but I learned through trial and error is that every time you’re finished with the 520 turn the fuel feed switch to off and let it run until it dies. That has worked for me for the last 15 years. Also, the paddles are crap, if you don’t replace them every year, they dry rot and are no good when you use it for the new season, they range in price from $37.00 to $60.00 https://www.amazon.com/Honda-Snowblower HS 520.
As for the MTD snow thrower again turn off the fuel feed switch after every use. (I have the Toro model similar to your MTD) Since both machines get limited use during most winter months the gas lead from the tank to the carburetor will gum up quicker. Come spring when you put it away, try and run them until empty. If you can’t put whatever fuel stabilizer you chose and run for about five minutes and the remaining gas will be good until the next season. Also, if you can store in a shed or garage it helps even more, outside under the deck with all the weather changes speeds up the gumming process.
