Looks like the choke every now and then decides to stay on: I can start and drive and everything feels ok. Then after letting down on the throttle to idle it will not rev and dies on me when trying to pick up revs. If I just move the throttle back to idle when it is just about to die, I awakens and runs smoothly on idle. After some fiddeling with they key it is "normal" again and no problem to rev... HELP!
