RE: 5500 Onan starts then dies, help please
Following a Long PRIMING today I pushed *start* and it fired right up. A couple of little hick-ups and I chose to hold the butterfly 1/4 open for an extended time, as in 5+ minutes as it continued to run fairly smoothly. Took CARB CLEANER and sprayed it in until almost dying, stopped and let it get back to idle. A few more sprayings and let it run until nice a warm then flipped the 2 breakers and 50AMP SERVICE resulted. Another 10 minute idle then both roof air conditioners PLUS water heater PLUS fridge with 30amps showing and RUN IT DID!!!
THANKS AGAIN and another check-out tomorrow hopefully will turn out OK.

Generator starts better than before then only runs for 4 minutes and dies. Checked pump with hose disconnected and pressure seems good so totally flustered and figure it's time for $$$$ and a pro.

RE: 5500 Onan starts then dies, help please
Broke down the carb today and the inside looked as clean as the day it was assembled. Didn't have any cleaner so put Seafoam through everything then reassembled and WHAM-BAM it ran but only for 5 minutes.
Same as before r.e.-shutting down, so held butterfly and it ran great.
THANKS for the replies.

RE: 5500 Onan starts then dies, help please
The seafoam did not work. You need to remove the carb fuel bowl and unscrew the needle jet assbly and clean out the 16 holes with regular carb spray. The carb is varnished/gummed up. Doug
Thanks :)
Will put your suggestion on today's "must do" list.

5500 Onan starts then dies, help please
2008 Onan 5500 that I neglected and did not run every month with load since May. Using start switch on the generator, first priming then start the gen. It starts and runs ONLY as long as I hold almost completely closed the butterfly under air filter. If I take pressure off the B-fly opens wide and sounds like gulping air then shuts down with code flashing 36. Reset code, prime and start up and again runs only by holding closed the butterfly. Sprayed plenty of Seafoam in to no avail.
Any ideas of problem???
TIA
