These genset are indestructible...only issues with them are carburetor gumming, which if it is get ready to fork up $275.00 for a new one...no rebuilt kits available. Trust me I'm on my 2nd replacement. However, prior to replacing carb check gas filter, air filter and oil level. Gumming can be avoided by working the genset an hour every month (personally started 20 minutes wkly) and fuel additive, I use StaBil. Havent had a problem in over 2 yrs...also change fuel filter every 6 months and spark plugs yearly whether it needs it or not. Now that I'm SoCal need to change the oil for hotter temps.

PS/ Also carry a spare full pump, fuel and air filter, and plugs.

Indestructible you say. Here is a picture of my Onan 4000 crankshaft after 1 hour of use.

Holy moly! Talk about catastrophic failure! I've seen high performance cranks come apart like that but never something as mundane as a generator.

Ya I was runnin a little nitrous on it. Just kidding. That's just the luck I have sometimes.

did the gen sit for awhile with out running it? those carbs are horrible and gum up easy. had to replace mine with only 40hrs on the gen because i let it sit for about 5 months with out running it. now i run it every 2-3 weeks if we dont have a trip planned i go to the storage lot and watch a movie. also put some type of storage treatment in the gas, i use seafoam but what one you use is up to you.

I had the local RV center do it .

Pretty easy to do. You'll just need a manual with the specs and a tester which displays hertz.

Wolverine68 is most probably right .
On my 4000 , I replaced with a new carb , new fuel pump , new fuel filter , spark plug , air filter , and new fuel line and it turned out to be the Hertz/rpm adjustment.

Was the adjustment easy?
