Generac generator isues

[blackshadow]

I have a Model 4709/5852(3600 watts) Generac generator. I had issues with it starting, ended up purchasing a new carburetor. It runs somewhat alright for the first 10 or 15 minutes, without load, then starts spitting and spudering.I have changed the spark plug, checked oil, changed fuel filter, and made sure fresh fuel is in tank. It seems to run fine at first with or without load. Any help would be appreciated.

Could be the ignition module - those usually show their ugly faces when they get heat soaked just with normal operation. Seems you've covered all other bases.

94-newmar is "spot on" but you might also check the fuel cap, some times the vent hole gets plugged and it creates a vacuum. Easy to test just take the cap of and run it, if it doesn't wheeze either replace the cap fix the vent or drill a new one.

Hey 94-Newmar Would that be the same as a Ignition coil assembly?

Yea, thats it. It's bolted on in such a manner that the flywheel magnets pass by it as it rotates... and will have the spark plug wire integral as well.
