Generator started running rough and stalling under load.
Cleaning and soaking carb in cleaner for a week helped but not enough.
I tried two Chinese carbs off eBay ($36 and $47 if memory serves). Both ran very poorly if at all.
Bit the bullet and bought Onan (Cummins) carb from ppl motorhomes for $290 + 10 shipping. Runs sweet again now.
Here are my notes in case of use to others:
Removal notes
Remove air filter; tight fit, need to pull front end far down and out
Remove gas line (plug if
Remove 2 carb bolts; my 3/8 socket on 6โ extension (1/4โ drive) worked well
Each bolts has a small flat washer
Warning donโt drop bolt or tools onto starter solenoid
Remove black plastic spacer (need to close throttle plate โ move linkage all the way toward motor)
Push tin plate away from carb to compress foam to help insert/remove carb
Remove ground wire with T30 for ground wire; needle nose pliers to hold engine wire to help disconnect solenoid wire connector;
Tip carb to slide linkages out
Installation notes:
Warning: make sure choke linkage is behind the carb (it can be in front and that hold the choke closed)
short 3-4โ socket extension help to insert and start bolt s
Other notes
Service manual say pump should be 3-4 psi but mine reads in the 2โs (on two gauges) and appears to work fine
