well just came inside from ******* with it and its running on its own, im sure i did the valves wrong cuz i didnt have a damn 4mm wrench so i had to make due with a cressent wrench snd that was a pain in the/////.... Sense its dark now i turned off my light to look at the exhaust and the leadpipe was glowing red so i turned up the mixture screw and got it about to where you cant see anymore glowing red,,, i think i can hear some ticking from the exhaust valve thow, may not have gottin it tightened down as good as i thought!!!But i can say the valve play from what i could tell was minimal,, if i even made it any better???
