Current setup on my Puch Maxi Luxe II
70cc Airisal kit
15mm Bing carburetor CLONE
Hi flo air filter (metal mesh)
Techno Circuit exhaust
Ngk spark plug
Second from top needle position
Currently I can get the moped to idle perfectly and I can WOT it on the stand and have no issues with it. As soon as I put any sort of load on it (ie. I get on the bike or I pull the brake without being on the bike) while trying to give it 1/8ths throttle it’ll die after a few seconds.
I’ve tried swapping different sized jets (I have a 82, 72, and 62 from the old carb), swapping air filters, adjusting the ring position on the needle, adjusting the idle screw, taking off the exhaust/putting on the original exhaust, checking the spark of the plug and the problem still persists.
I think the issue is a fuel/air mixture imbalance but this is my first bike so I’m not too knowledgeable on them. Is there anything I’m doing wrong or something I haven’t checked yet? Any suggestions?
