Total run hours: unsure, but has been installed several years
Fuel source: NG or LP: LP
Here's my saga any help appreciated...Generator was working when I bought a house 1 year ago. Started for the weekly run most times. Infrequently, it wouldn't start and give an overcrank error. I replaced spark plugs, old ones seemed ok though, but it seemed to help with starting. Then months later I got an overspeed error. I determined the stepper motor gears went bad. I replaced the stepper motor, but when disassembling, i broke the intake airbox getting it off, so i replaced that as well. I ensured the ng/lp was on lp, cycled a few times. Engine won't start. I took airbox back off, even removed the ng/lp slider to ensure it was not blocked, reassembled, won't start. I purchased a manometer, tested gas pressure at the regulator ports, have 10.5". I had a service tech come out. He stared it with a spray of starting fluid and it ran. He concluded bad fuel regulator. I purchased a fuel regulator, install, still won't start. Tested the pressures again, all are 10-11.5". i checked the valves and appear to be .0025 which is in spec. I tried to start it today by putting my fingers in the venturi's and cranking on manual and it starts right up no problem, runs normally. I looked at the choke and it appears to move like it should when it is cranking, opens fully at speed. The the chock plate seems close to the venturi's not sure how to adjust to get it tighter and still allow it to move. I"m at a total loss on where to go from here. One other weird thing, I placed it in auto and set the exerciser, when it started cranking I put fingers in venturi and it started, but the choke is staying closed and it is not running at proper speed so I'm not sure what that means. If I start it in manual (with fingers in venturi) it runs just fine.
