Good news! Just make sure theres a fuel filter between the carb and the tank :idea:
Also, when your not running the genny, make sure the fuel shut-off is always closed, Just in case... ;)

Yes there is a fuel filter inline before the carb.

Still behaving itself this evening, checked the oil fill plug and still had only oil in there like it's supposed to be.

I started it up and let it run for about 15 minutes. One thing I noticed is that it runs rough when choke is on RUN, I had to have it about 1 notch below that to run smoothly.

I need to do something permanent with the hose coming off the crankcase to keep it away from the muffler and heat of the engine. Also to plug up the end to keep dirt out as suggested earlier.

I'll check the oil again tomorrow and may even drain and replace it just in case I didn't get all the gas/oil mixture out the last time.

Thanks again for all the help.

It's running lean. Try adjusting the high speed jet. If that doesn't work, you may need that pump.

Only running with a little choke? its running lean, you may need to clean out the main jet, or reattach a new pump, if the old one can't be rebuilt. I found it easier and cheaper just to buy a new pump, than to try and rebuild those.

Yep - clean the low speed ( pilot ) jet & it'll be back to normal. The pilot is always the first to clog due to it;s size. Yours is just partially clogged. Clean every passageway & jet you see in there, then drain the float for storage & you'll never have a problem again. ;)

Just wanted to resurrect this thread for a final answer on the fuel pump necessity on this generator in case anyone with a similar issue happens to read it. It needs the fuel pump!

All the times I had run it after removing the pump and adding a fuel filter I did not have anything plugged into it and only ran it for about 15 minutes. And other than having the choke lever one notch below RUN, it was fine for those short runs.

We haven't had power since Monday so the generator got a good workout. It was running progressively worse and I had to mess with the choke setting a lot, gradually moving it toward full choke. It turns out the fuel supply wasn't keeping up with engine demand, especially when the two pumps, fridge and freezer were connected. Today, I finally remembered that I had removed the pump and went and bought a replacement, installed it and we are back to smooooth generator power.

I am glad the issue is finally resolved.
The old pump must've been shot.
Yes, I mentioned back in January, a new pump may be required to get rid of the 'lean' condition.
