I haven't even tried yet.
I picked it up for about $20 from a guy I bought a bunch of engines from. it's kind of a funny story -- and a warning!
I was looking for a used 5 hp for my go kart last year. Turns out small engine repair guys are hard to find these days. The man I used to go to a long time ago had passed, but after a lot of searching I finally found a guy on the other side of town.
Said he had an 8hp engine and I went to get it.
His backyard was stacked, wall to wall, with engines he was fixing, or junk engine he couldn't bear to throw out. The more we talked, the more he kept offering me. Hey, why dont you take some of these? Want a pressure washer? How about this? That? The other!
I'd just taken my car, and couldn't haul anything else off, but I told him I'd be back for a couple of 3hp engines and the junk tillers/washers/whatever they were still attached to.
So, for around $120, I got:
4 3hp engines
2 8hp engines
2 10hp engines (the one you see and another that's attached to a generator).
the engines we attached to:
water pump, air compressor, power washer, generator, and something else. What a pile of stuff! And the guy was still trying to get me to take more! Said he was "cleaning out".
Anyway, turned out the 8 HP's ran but the output shafts were specifically made for the generator and water pump they came off of. Weird spline shafts. Rather than fight failure, I tossed them. 3 of the 4 3 HP's were good, and I've yet to try the big boys. But I've got a new magneto conversion for them and I'll bet they'll be great.
