Why does my Harley Davidson stall when I idle?
It always starts easily when cold and idles well, but after a few minutes, if I’m idling awhile to get out of my driveway, the idle will fall and the engine will threaten to stall. If it does stall it’s hard to get started again, I have to give it a little throttle to get it to start and stay running.

What causes a car to stop when idling?
