A home we bought has a Homelite 5500 generator as a backup. Initially it wouldn't start.
The Problem...
Now is starts every time easily with full choke and I can move it to the run position, but it runs roughly, cycling fast and slow with some backfiring. I let it run for 20 mins to 1/2 hour thinking maybe it would need to run for a bit. However it never improved. When I went to shut it off, I moved the choke to about 1/2 and it ran smoothly for about 1 minute then ran rough again. My thoughts are it may be a matter of either timing between the coil and flywheel, or adjustment on the fuel/air mixture. However, this model of Briggs / Stratton has a fixed adjustment, only allowiing about 1/2 a turn. As a result, I'm not sure where I should focus my time next.
What I have done...
I cleaned the carburetor and fuel parts, replaced gaskets and fuel hoses, fuel filter, new spark plug, flushed the fuel tank and added new. As I mentioned, it starts right up but runs roughly. I've tried adjusting the fuel mixture screw but it doesn't seem to make any impact. Due to increasing the choke causing a minute of smooth running time, I thought maybe it wasn't getting enough fuel for some reason. I'm kind of at a loss at this point and thought I would inquire for some suggestions.
I attached the Briggs / Statton Manual if helpful, and my engine information.
