I recently tried to install a fuel filter on the fuel hose of my Puch Maxi. After doing so, it would not start. Thinking that the filter was obstructing the fuel flow, I disconnected it and reinstalled the hose as it was originally. The moped will still not start.
The gas gets into the carb which is clean as far as I can tell upon openning it and looking at it. The spark plug connector sparks when I hit the pedals, but the thing just won't go. It will sound like it's running only if I have the throttle cranked and am pedaling. The second I whined down the throttle or stop pedaling, the thing just dies.
What could be wrong? It was running just before I put in that damn filter!
