Thanks Frank & Born to be wild. Those are both great sources. I'd not looked at the stuff under the technical tab yet on jawamoped.com. And Frank, that is exactly what i was after for the intake/carb detail.
I took apart the carb one last time and cleaned it completely with carb cleaner, compressed air & copper wire. Got the same results. still leaks gas as the needle valve isn't airtight. Bike only starts on full choke, engine seems to race as if at WOT, then dies off after 4 or 5 seconds. If i try to work the throttle, it dies immediately. With the carb completely cleaned, i was expecting to at least get the thing to idle. Any suggestions?
Also took apart the petcock and the little cork disc with the holes had started to disintegrate, so I'll need a new one of those to get that right.
was probably a bit too optimistic about getting this thing on the road right away. When i bought my 79 qt50, I pulled & cleaned the carb, petcock & gas tank. Changed the oil and put in a new spark plug and it's been up and running great ever since.
