Okay so I just bought a chp motor off here a month ago. I set everything up and it started after a few kicks . It seems that the bikes running lean . It'll start but it doesn't want to stay running ! It currently has a 130 main and a 51 pilot. The needle was one up from the bottom and I ran the clip two notches higher it diddnt seem to any bit.i live in newenglnd where were at sea level . The motor rips when it's wide open but as soon as ur off the gas of dies. Any help would be appreciated. This website has helped me out a ton now that I have a mini!!

Was the engine brand new or used? Either way it sounds like your pilot jet is getting clogged or your idle screw isn't set right

does the idle jump back and forth ? or does it just slow down and die ? could be an air leak
