Hi all, I have a 1973 646 with a VD 75 Carb on it. The top of the carb is fairly warped and leaks, I've replaced the gasket with no improvement. Is there an after market replacement carb? Or can I use a later model carb? Ebay has New Carburetor Carb For ONAN NOS B48G B48M P216G P218G P220G Replace 146-0496 146-0414 146-0479. It looks like it might work but not sure about the throttle linkage. Any help would be greatly appreciated.
