Hey all, I have a 53cc 4 stroke huasheng that I got installed. It wouldn't clear my frame with the outer part of the air filter box, so I left the inner part of the airfilter box on (just the side with the bolts exposed) and ziptied the foam on. It works well, but I would assume its running lean since it now has more air flow. When I tried to start it for the first time, it did not want to start at all. Choke or not. It would start if I gave it half throttle when pulling it, but then immediately die. Weirdly enough, turning the fuel screw 3/4 of the way out from seated allows it to start first pull and idle normally. Isn't this leaner? When I tried to make it richer, around 2 turns out, it would stall and die and white smoke would come out of the carb. Is this normal? So I put I put the fuel screw back on 3/4th of the way out and rode it for around 20 miles or so. I take the plug out and this is what it looks like. Am I running rich? lean? I've tried looking at the forums for answer and I couldn't figure this situation out.
