Ok so I got a chance to split the cases and it has had water in it. I am going to split a motor off a utility and fit that crank,rod,piston and barrel into the earlier cases and use the original head.This way it keeps the correct engine number. Inlet port is the larger diameter, is there a thinner sleve I can get so I can use the original carb or do I have to make one, if so what material should I use? The only other downside is that the barrel does not have the bolt on transfer ports but I doubt anybody would notice this seeing it is an early sixties model first of the utilities.
