I have a 2500 LP Onan also (Year 2000, maybe spec K?). 6 months ago it was hard to start, was surging badly at no load and had trouble managing a sudden load.
Found by spraying carb clean on the air filter that it was running lean.....idle would smooth right out.
Ended up yanking the demand regulator, getting a rebuild kit on Amazon for ~$60 and using only the diaphragm.
Now it idles normal and runs perfect under load or not.
Would you have a part number of the kit you bought? How were you able to determine that it was the correct kit for your generator?
Thanks!
