Has anyone fitted their cowl with only the engine case and crankshaft installed? As opposed to assembling the whole engine and letting it sit for a long time subjecting it to rust etc.. My main concern is if the later installation of the exhaust will than be more complicated and what size propellor spacer would I need for a fixed pitch prop in a newer style cowl. My tech counselor advised me to do this and while I trust his judgment I would like to know if anybody has done it. He said the important thing is to nail down the gap between the spinner back plate and the cowl.
