Spent a little time yesterday looking things over and decided I'm definitely going to machine another center carb. I want to keep the chokstat mounting points in case I end up with one of those or using the manual choke parts I have.

Ideally I want to run a factory style well mounted chokstat, probably get one for an 80s 318 to have electric heating too. And yes, I'll have to modify the rod for it.

Also I want to reshape the center airhorn around the float adjustment for the rear carb.

There's vacuum passages in the bases of the outboards that will need to be plugged, the surfaces of the manifold aren't big enough to seal them off. I'm thinking JB weld or solder, any other ideas?
