its a 175 XR4 power head but has 150 blackmax carburetors on the motor. I have found that I can’t find any floats or bolts for the ones I have (one of the bowl bolts broke off) is there anywhere that have parts for old motors, and since I can’t find another bolt to fit I am going to try tapping the hole to the next size screw, but for future references will any 150 carburetor fit the motor? Or be able to put 175 XR4 carburetor on the motor? Really trying to avoid buying a new motor but my resources have came up with no luck and I can buy ready to go carburetor sets off eBay but need to know if they would work.
any help appreciated
