Last weekend I had to dig out my generator for the power outage. It's a Homelite LR-4400. It started up right from the get-go and ran fine, but the moment I set the choke from "start" to "run" it would stall out. So I ran the 20 to 30 hours I needed in the full choke position. Even warmed up it would stall out if I moved it toward "run." This unit was used only once before - during the great eastern blackout of 2003. So this unit is rather new and untouched (untweaked), except for the break-in oil change, and stored indoors in a dry basement. What could have gone wrong during the 11 years it sat? It seems I should be able to set it in the "run" position while running.
