Troy-Bilt Horse - engine replacement

[dhermesc]

I have a Troy-Bilt Horse II, it has the HH60 Tecumseh engine. I would like to replace it with a larger engine but am limited by the 3/4" drive shaft pulley. Is there a 1" drive shaft pulley that will work? Is it a later "Horse" part?

I have a wrecked Horse I found by a dumpster. Looks like it fell off a truck. The engine is a Kohler K161T 7hp with a 3/4" shaft.

I sold the Tecumseh 6hp off this tiller for $60.00 and I bought a 10hp B&S from the smallenginewarehouse back in 2006. Hal
PS: Those 7hp Kohler's are good engines.

I've been looking for a replacement engine but most of the larger used 7&8 hp engines I've found have a 1" shaft. I know I could go with a new one from Small Engine Warehouse but one of those costs more than I currently have in the tiller.

I know that some of the older Horses have the 8hp Briggs engine - I just didn't know if they had the 1" shaft or if they were something special with the 3/4" shaft.

My Tecumseh is still running, but its on borrowed time. When I bought the tiller the owner started it and let it run for a few minutes. It progessively sounded worse and started to squeak - he suddenly shut it off and announced he had forgotten to put oil in the engine. The selling price immediately dropped as a result but I still bought it. It currently runs decent with a few puffs of blue smoke but it seems really low on power (I wonder why?).

I know the Kohlers are good, and fairly cheap to rebuild if you start out with a complete engine.
