It's the carb, the bore is too large. They put a 40 engine size carburetor on them. Why? I have no idea. But swap it out with a CMB or NovaRossi or any other .21 carb and they should run very well.
 
Interested in the VZ-M. What parts do you have to go with it, and are they new parts?

Thanks,
Steve Ball
 
I'm sure I have what I think is an Irwin nitro pipe. And last I looked a piston and liner. Both engines. Use same piston and sleeve assembly. Both engines have the water cooled head, not the plug in water cooled plug. (It wont stay in when boat gets up to speed) there NOT worn out.also have a few header to engine seals
