I got the Kohler in today, so I threw it up on the base along with the gen head to see how it fit. Its gonna work just fine
Still a bit of work yet to finish the base. I forgot to order weld nuts for it, so I can not weld up the bottom plates until I get them in. Need to weld in some support bracing to hold the engine and genny in place and then for this Kohler I will need to relocate the mounting holes back 2 inches. I figured Id have to do this. One of those things where you need the parts first before you design.
