82 GL500, 78 CX500
I've had an 82 GL500 for awhile now and thought I had a persistent problem with one of the carbs. I got a second carb set with an engine I bought and rebuilt them. After installation and checking, the engine still had the same problem. Id twist the throttle a little and the engine would at first hesitate and then rev. When I released the throttle, the engine continued to rev even with no throttle. Eventually the revs would drop back down to idle. After some thinking, I'm beginning to believe the problem might be a sticking ignition advance. I haven't pulled that off yet to check it because I wanted to find out if anyone had a similar problem?
