I mentioned this in my long running thread " My 60th birthday present" but I know not everyone reads it and I am looking for some input.
Yesterday I had my BS38 carburetors off and apart for cleaning and to fix an intake leak, the leak was making my idle erratic and I thought it was making my throttle hang up
So everything cleaned and re assembled, back on the bike and fired it up. Intake leak was gone , the bike started easily and idled well, and runs good. Then this morning I took it out for a little test ride and before I got far at all the throttle started hanging open, making the motor race.
When I got home I disconnected the throttle cable and worked the throttle manually and it doesn't snap shut like it should, it hangs open and you have to wiggle the throttle shaft to get it to close.
I will probably pull the carburetors off next weekend and take a look, but not sure what could be binding.
When I pulled the carburetors apart, I didn't touch the throttle shafts or butterfly's.
But could it be maybe the butterfly's dragging on the carburetor body? I can't think what else might cause the linkage to hang open.
A little background.
This just started happening PRIOR to tearing down the carbs, it has worked perfectly before.
I have a Pamco E ignition and the electronic advancer.
The throttle cable is new and routed exactly the way the manual shows to route it.
