That's funny you mentioned that....Seafoam. I use that on my boat all the time and told Dad last night we should try running that through the gas tank. I have one can already, but will need a couple more. They brought the motorhome in completely filled up and I think it holds 75 gallons. He said they put Stabil in the gas when they filled it up, but I don't think adding Seafoam to it will hurt anything.

Do you think it would be a better idea to hook the generator up to say a five gallon tank of gas heavily concentrated with Seafoam to get better results ? Getting to the supply line hose from the tank to the generator fuel pump is really not that hard to do.

I thought about taking the carburetor off and soaking it overnight in carburetor cleaner, but was worried it might damage some internals or such that I wouldn't be able to find replacements.

Thanks for your helpful replies.

With kind regards,

did ya happen to check the air filter?

I put the Seafoam in a squeeze sprayer and removed the air cleaner.
I sprayed into the carb while it was running and made the engine stop.
I let it sit for an hour and when I started it up it spat a lot of crud out the pipe.
Don't squat in front of the exhaust pipe while adding the Seafoam or when starting it up afterwards.
After treating my gen set I had to lower the idle because it sped up so much after being cleaned.

About the air filter.....it is fairly new, but the generator reacts the same way with the air filter installed and without taken completely out.

I'll try the Seafoam spray-bottle technique tonight and let you know the results.

I just want to be sure I know which is which......the main-metering adjustment screw is the one on the bottom of the carb....(altitude adj)...correct ? The small screw at the top of carb with plastic phillips-head screw is the idle adjustment screw...correct ? I wish I could find a schematic of this carburetor, but haven't been able to find one.

Again, thanks for the tips and ideas !

With kind regards,

Well I tried the spray-bottle Seafoam tip, and while it definitely seemed to clean out a bunch of crud, I still am having the problem of it flooding out under the load of both ac's running.

I watched the governor try to "feed it fuel" to keep the rpm's up when the second ac is turned on and now I'm starting to think that maybe it trying to give it too much fuel while under the load of 2 ac's.

I'm wondering if the governor linkage maybe out of adjustment and it is opening the throttle too much for the required load ??

Any suggestions / tips are much appreciated.

With kind regards,

If I understood you correctly you mentioned above that you changed the RPM setting.

If so that will change the frequency of the output volttage. The ACs may not like that and might be drawing too much current.
The governor is supposed to keep the RPM at a constant speed, opening the throttle when the loads try to drop it. That keeps the RPM constant. The electronic regulator keeps the voltage constant by varying the current into the rotor.

You might want to check the frequency and see if it is 60 hz or not.
