You are bidding on a Tecumseh Hsk850 from a snow blower. Was built for a Go Kart. It WAS rated at 5 HP but I ported the cylinder so HP should be about 10HP. The governor is removed. Engine RPM's need to be kept below 7000. It has a 1 inch output shaft. I will include a #35 sprocket for a jackshaft. Jackshaft not included. You can put a 1 inch clutch on if you like. The engine is very light. With the right gearing and kart, 60mph should be easy. I built a homemade expansion chamber for it too. It's not perfect but looks and sounds awesome. No carburetor is included. It needs a Tillison HL series carb. Or something similar. I will include a KX65 carburetor. You'll have to adapt it to the engine.
It starts first pull. This is a racing engine so it's as is.
I have a 100% feedback so bid with confidence.
You will need to adapt the carb or purchase a carb, and fabricate a motor mount and clutch. Otherwise it's ready to run.
Note, expansion chamber was made for this engine but shown on another engine. This is the one you will get.
I have a video of the engine running but can't post on here. If you'd like to hear it run, let me know.
