i got my FCR carb last week or so, and I have been jetting it out, and right now I'm at a 200 main jet and its still lean:huh ! I took it out to Silver Lake like that and it ran great, but the plug was still white. Thats pretty crazy, the guy who did my porting and did a few other 440's like mine said the biggest he heard was 180 and thought that was high. he was kinda baffled too. I'm gonna give it to him for a few weeks and let him play with it. Anyone heard of this?
