Ok, I just got back from the hardware store and I got 1/4-20 bolts lock nuts etc and I got my engine all mounted then took some pics then test mounted the cowl and it's a good space. The bolts were a bit small so I had to take 1/4" off my standoffs. The prop would have been like 3/4" from the cowl but now it turned out about a half inch away. Got a bunch of pics so I'll post like 5 or 10.
