Worked on this snowblower I bought last year. It's a 2 cycle and I'm told it was produced in low numbers; it was new in 2005 when 2 cycles were just being phased out and it just wasn't a hot seller when there were otherwise identical 4 cycle machines sitting right next to it.
The engine bears a strong resemblance to a Lawn Boy Duraforce engine. They aren't the same, but since Toro owns Lawn Boy, I wouldn't doubt they borrowed a lot of engineering from it, though I think it was actually built by Briggs for Toro.
It ran sorta okay when I bought it and while I used it last winter but it wasn't quite right. When I started it for the first time this season last week it revved so high it sounded like it was gonna launch into outer space. I suspected crank seals, I pressure tested it and they were fine so I pulled the carburetor and found the problem... Chinese knockoff carburetor.
It's super clean, no issues with it being dirty or anything, these things just suck. The tolerances are way off and they are always jetted way too lean and either surge or do what this one is doing. Every single one of them i have come across runs like sh*t. So it needs a carb.
So don't buy those cheap $15-20 carburetors off of Amazon or eBay. Buy a rebuild kit or new OEM carb.
