I've been curious if another oem carb would solve the issue I've had since opening the airbox. I made a thread about it a while back describing the problem, and I've never really been able to solve the issue. I had a lot of problems with the vitos fuel screws not letting me idle unless they were like 1/8th turn out. Anything over that and it would get rich and die. Not sure if that qualifies, but maybe we could agree that I'll clean/assemble the new carb and if it doesn't fix it then I'll send it back or offer it up to someone else?
