I have a 2002 E-ton Beamer. It was in storage for the winter and had made some repairs to the tail light and exhaust port. It is currently unable to start. It cycles its 49cc engine but fails to fully start. I had attempted to diagnose this by using started fluid. it worked but it only lasted relatively to the amount of fluid I use. I assumed it was a fuel injection problem, so I removed the fuel valve and stuck it in a bottle to see the flow. It appears to be flowing gas but stops at a certain point. I checked the air valve in the pressure-based petcock, but nothing seems to be wrong with it. The air filter doesn't seem to be the issue either. Can someone please help me in finding the problem and fixing it. I need this bike to work as soon as possible.
