Anyone wanna check my diagnosis?
My guess: stuck float valve in rear carb.
Cranked 'er up Saturday intending to ride. Started, ran a little rough, got rougher... wouldn't run without the choke on. In fact, it only runs with the fuel valve OFF, if I turn it to ON, it quits.
Front plugs are good. Rear plugs are wet with gas. Oily fuel drips from the rear exhaust joint at the block when it's running. Major gasoline smell out the back (the cycle, not me). It will idle, but rev it and it backfires and blows out a puff of smoke.
Of possible interest: about 25 miles ago, it quit on me at an intersection. Wouldn't idle, but would rev slowly higher and higher until I cut the switch. I finally spotted that the rear carb air boot had slipped off. I replaced and tightened it and the cycle ran fine for the rest of the trip.
Any other likely suspects besides the float valve?
