I've been lucky enough to get these things working great, and have been an advocate for the new race carbs. BUT, I'm on my third one and the same **** problem keeps happening, mounting Neck breaks. I gotta say they run great but it's not worth it when they physically break every month. So for the few (most of you) that deserve an "I told you so" or a "see that's what you get" **** cheap cast pot metal. "If it ain't broke, Fix it till it is"
