I recently picked up a great 1978 Moby 50v, got all its parts stickers and covers only thing is, it doesn't stay running for long.
Idles or rides fine for awhile then, just dies. It left me stranded in the Philadelphia ghetto the other day haha. I have cleaned the ever loving crap out of the carb, checked for airleaks, installed an external condenser, drained the tank, cleaned the exhaust and, replaced the inline filter to no avail.
The local moped shop tells me getting rid of the Gurtner carb will fix the problem. Is there anything I am overlooking? I told them to go ahead and order the part to retrofit on a different carb.
