Editor’s note: I am not sure that the numbers on the regulator represent PSI as I say in the video, they may just reflect restriction size with 1 being most restricted and 5 least restricted.
Fighting carburetor flooding issues can be frustrating. What has become more and more common these days is aftermarket mechanical fuel pumps putting out too much pressure and overcoming the needle and seat. If you can’t find your problem anywhere else, try this.
