Believe me/ some of the old Go Kart brand machines were horrible with centered adjustment slots. Pop and I milled the swing mount slots in the 1200's longer, but you still sometimes needed a shim under the engine. The question brought back evil remembrances of HALF LINKS in our chains! This was in the days before riveting chains. Even some of the side plate mounts we usually get have too short a slot for vertical adjustment. Rick Violet makes some very nice side plates, and I asked for longer slots. He is making them longer now. Kudos to Rick!TJ
