We purchased a new TH this fall, it has a onan 4k generator, that has never been started. Should we fuel it up come spring and run the monthly maintanace routine, or should we leave it unstarted until we absolutley know we are going to use it. The trips we are planning this year should be at campgrounds with hook ups.

I would start it, warm it up, run it with a relatively high load for an hour, then do the normal maintenance. Until you start it you don't even know if it works, so you don't actually have a generator - just the promise of one. You need to verify it and learn how to operate it and then you actually have a known proper generator.

Did the mfg or dealer put in enough gas to try it out? If so you need to excerise it or your going to wind up with a gummed up carberator. Ask me how I know.

Definitely get it fired up. Break it in according to the instructions and then run it about once every three weeks to keep the fuel system clean and to "exercise" it. Excercise means you need to put a load on it to keep the generator in good operating condition. Also, put some Stabil fuel stabilizer in the tank.

As an Ex-engine professional, my advice (even when free) would be to:
A - Read the owner's manual
B - Check the lube oil level
C - Start it
D - Break it in carefully
E - Run it at load - when you are certain of its condition
F - Put it to bed for long term storage.
This last means fog the engine and dry out the carburetor. The manual may say more, if it does, do it all.
If it is more than a year before you use it again, change out the lube oil, it only last a year when it is open to the air.

Does he have any idea what he is saying??
I have two generators, one in the coach and one for the house. They are both over 40yo and will start and run at load anytime I hit "Start".

I imagine that it would be good to know that it works before the warranty expires.

Just seemed like a waste of time and fuel to run it monthly for no reason.

Thanks.

There are two reasons to run it monthly. One is to keep fresh fuel in the carb / injectors, and keep the oil circulating in the engine so nothing drys out. The second is to dry out any moisture that works its way into the windings on the generator. The buck or two of fuel you waste every month doing this is far less then even a simple carb rebuild. You will spend more on oil and filter yearly then fuel needed for maintance.

I guess it probably would be good to know if it actually worked before its out of warranty.

Just seems like a waste of time and fuel if I'm not going to use it for a year or more.

Thanks.
