My name is Austin and I'm looking to get my 1984 Puch Maxi to stop dying on me. She starts up nice, idles fine, and rides okay for the first five minutes. After that, I'll be at full throttle and a complete standstill on flat ground. I have yet to clean the carb and exhaust, but I'm assuming that those aren't the source of my problem given that she will run at first. I'm guessing this has something to do with the condenser? Is there a good way to check that that is what's wrong?
