Here are 2 examples of how to add a "Mikuni" carb to your flathead. The red one has a PZ26 with EC Carburetors 407int intake. It wouldn't work with my genuine VM22 Mikuni. You could see the O ring on the back of the carb. I had to slightly enlarge the bolt holes in the PZ26 to fit over the intake studs but that was easy. This intake was under $50 and has a pulse fitting. The Caddy engine uses a Briggs intake part # 691922. It is the original intake off the red engine. In order to attach the carb I had to add studs to the intake and widen the bolt holes in the carb. There is no pulse fitting and this intake is discontinued. I have seen it avaliable but it is now over $50. These intakes work on the blocks with 3 intake bolt holes. The 407int has a hidden bolt holt to make it work on a 2 hole block but it doesn't quite line up. I had to do some work but I got one to fit on a 2 hole 3hp block but that will be a different post.
