Thanks Jude, helpful information!
I'm not using engine for aircraft, but I am using it for hovercraft, so weight is also a big issue for me. I left the flywheel on, but it is from auto tranny, not too heavy. I gutted the pressure plate, machined it down to min thickness and made an adapter for a flex coupling to the shaft.
I made a bracket and kept the soob starter, even though it mounts from the rear.
I want to strip all the emissions and extras off the engine for a cleaner look also.
It may be easier than i think, it's just new stuff to me.
