Hi Can anyone help please I have a 2004 vespa px 125. My problem is the mixture. I seized it up several years ago and had a new piston so it is slightly oversize. I recently put a SIP road 1 exhaust on it and now can't set up the carb. My main jet is 102 the atomizer is a BE3 and the air corrector is a 160. The idle jet is a 50 - 140. I have wound out the mixture screw 2.5 turns, the throttle is good with no flat spot. When i check the plug (ngk b7hs) it is white with speckled brown bits, which indicates overheating. plus at 30 - 40 mph in 4th gear it is slighty boggy, over 40 nice and smooth. Any suggestions would be very much appreciated. Thank you

I think the std atomizer is a BE5, the BE3 is for a 200 so that might be running a bit rich in the mid range.
