My first submission to the board...
I own a '79 Puch Maxi II that I purchased a month ago with only 350 miles. I've been riding the bike and it has performed flawlessly until this morning. I was about a mile from home when the bike started to slow (from 30 mph) and lose power. I was able to maintain about 10-12 mph and could only accomplish this by twisting the throttle to the half-way position. Anything more and the engine would bog down and want to die.
The bike is not out of gas and the mix is set at 50:1. I also opened the gas cap to ensure a vacume wasn't occurring that would prevent normal operation.
I read through many posts and did not find anything that addressed this issue.
I'm sure that this is related to the carb and have a rebuild kit that I'll be installing but would appreciate your expertise before I get in over my head.
Many thanks in advance!
