Im switching out my old engine with a new one. The old engine (pictured) had the cooling fins on the #4 cylinder ground down to make installing the rear adapter for the mount easier.
I can't get the mounting bolts into the adapter without hitting the fins and I don't want to grind them off, Nor do I want a shorter bolt. Do I really have to grind off the fins? Shorter bolt seems like a bad Idea too. I'm open.
