I see Fire (or spark) in one carburetor

Re: I see Fire (or spark) in one carburetor

I took the flywheel off today and checked the magnets, there tight, the stator looks clean, the wires to the timing base looked good, no indication of burn. The only thing I saw that looked "not to be right", was that the wires going to the timer base from the powerpack were going thru a retainer (the retainer held the wires secure and out of the way from the flywheel)
But with the wires going thru the retainer, it held them in a bind so that the timing base could not open all the way as you give the throttle.
It could open part of the way, but not all the way.
Other words: the wires were in a bind and keeping the timer base from moving all the way around. Now I don't know if this is the problem, but that is all I found that look to be wrong. If it's not raining tomorrow I'm going to go try it out. If it don't idle good then, I'm going to clean the carbs.

I think it may be time for a bath and rebuild like Dhadley said. Check to see if the timer base moves smoothly without sticking when you advance the throttle.

Take the airbox cover off & observe whether the throttle plates are parallel.

Also, the timer base should start it's travel *before* the throttle plates start to open, else she'll fall flat when you try to accelerate.
