Help Me Fix My Snowblower

I got this thing given to me and I'm beginning to see why. I'm near ready to kick it to the curb. It runs like crap. Runs a little better when choked. I've had the carb off a couple of times looking for a blockage. Main jet is clear. Carb was soaked for 48 hours to clean. It's getting fuel. Removed fuel line and filter and replaced with another with no change. This should be simple there's not much to it. It's a Honda HS35.

A lot of small engines are designed to run with air cleaners. The air cleaner provides some flow resistance.
You reminded me that I have to get my snow blower up from under my deck.

I bought a generator that had a similar problem, it was cheap and almost brand new but would only run properly with almost full choke. Without choke it constantly surged. I must have had that carb ( engine is a Honda GX270 clone) apart so many times I could do it in the dark and always it was the same. I too was ready to throw the thing down the hill, I cursed the smarmy mongrel that sold it to me, and his sisters and his mother and his neighbors....his neighbors mother....
I finally ordered a new carb online, it looked the same but didn't quite fit because of the air filter arrangement. Oh well, I started swapping jets and other bits to see if things would improve-nope still surging away. According to my research, 99% of the time surging is caused by lack of fuel, and thus it was it the end. There was a little plastic plug on the side that seemed to have something to do with directing suction to an idle jet, when I swapped the only-slightly-worn looking O rings on it for the ones on the replacement carb-bingo! Instant success, the bloody thing just purred away no problem at all.
Maybe, just maybe, you have a similar problem.
Best of luck with it!

With the tightening of emissions many small gas tools are getting harder to keep running properly. They need a richer mixture then the carb is set to supply out of the box.

Thanks for the replies. My engine is a G150. Not much to the carb and from my understanding the carb is only used on this snowblower. There are no plugs on the carb body.

It's running too rich. Backfires through carb and spark plug is dry black. Tried a different plug with same result. Float level appears to be good and isn't adjustable. No apparent air leakage around carb base.

It doesn't so much have an air cleaner. Not too much dust blowing around in the winter. All it has is a metal shield with a bit of very coarse wire mesh in it. Putting it on makes no difference in how it runs.

I have an Ariens, pretty large one. Mine has no air filter-pretty sure few do. I have to "play" with the choke every time I use it. I think your issue is def. Related to fuel...type/flow/octane/additives, etc.
I learned I have to drain the gas each spring,use Seafoam and put in Mobil 89 octane. If I change any of that, I have issues with it.
Good luck!

I have a big Tecumseh powered snowblower, I think it's 11hp? Surges like crazy too. Weird part is that when it's under load it smooths right out! I read something on the web about cleaning up the jet to fix the problem, but I haven't gotten around to it yet. I know you've already cleaned your carb so it's probably not that. Drives me nuts with the surging! I've also got a little single stage from Crappy Tire. It has a chinese Honda knock off engine on it and it purrs like a kitten!

I've also read that the governor can cause issues, but I haven't looked into that much.

Be nice if we didn't get all this snow in the winter, I'd glady trade in my blowers for more lawn mowers anyday!

I was going to post yesterday but got busy. I'm actually thinking that it is a governor problem. I have two identical snowblowers. One I've owned since new and this one that was given to me. Yesterday I hauled mine out and put some gas in it. Always starts on first tug as does this 2nd one.

Started on choke and after about 30 second I opened the choke. Right away the governor linkage went way over and the settled in at a steady RPM. The second unit the governor doesn't move. I do recall it moving on one of the many occasions I've now tried this thing but right now it's not moving unless I move it. When I do I can get it to run steady. Had the thing stick at what sounded like 6000 RPM. Thought it was going to blow up.

So looks like I need to take that engine out of there and see what's going on. More projects.

When I set my snow blower to run right in the dead of a New England winter, it runs way to rich at temps above 30F. (Your mileage may very.)
