| Are you talking the front stub shaft? It is straight and too large for the clutch/pulley |

| Also should there be engine mounts or were the Onan base configured differently to raise the motor. Should the fan be blower or vacuum style. What size of pulley should be on the hydro side. |

Well, the engine looks like my engine other than the flywheel and crankshaft. My flywheel is a large cast iron version half the size of the one that's on your engine. Obviously, the engine is for some other application, but can't see why you couldn't use it with some mod's. Also, my engine was bolted directly to the frame but does have a bolt/nut setup on the bottom of the engine mounting tabs on all four corners located between the engine and frame which lifts the engine a tick. Kinda' strange when I first pulled the engine out this Spring, but its gonna go back in the way it came out. I've was working on and off the engine a while back, and I left the stud/nut setup alone.
