My Gator 620i ran erratic and continually had gas in the oil. With instructions from John Deere dealer I cleaned the fuel injection parts and then started putting 1/2 pint Sea Foam in each 5 gal of gas. Still get gas in the oil but at least the engine is running OK. That's been over 150 hours ago.
However now I'm getting a squealing sound that gets louder as the engine gets warm. Just listening to the engine it's loudest new the center of the engine near the fuel injection system. The fuel pump makes a similar sound but a little lower frequency and not as loud. Any ideas appreciated.

I have a heater for the cab and it wouldn't let the oil warm up to burn off the gas.In the winter time I would have to leave it running a lot more than I wanted to to keep the oil level low.As far as your motor noise I had a stick get stuck in the flywheel cover and it was rubbing

Thanks for the comments. Never had a heater but I go short distances so the oil often does not get warm. As for the noise doesn't sound like a stick noise as it's a high pitched continuos sound, but I'll check it. ....

Problem was the fuel pump. Had to take it to the dealer to replace it and the fuel filter as couldn't get a wrench into it to remove the pump. They changed the mount so next time I'll be able to get to it.
Now have the engine running erratic even though I'm using Sea Foam in the gas. Tried spraying carb cleaner into the fuel injector assy which helped a little . Just changed out the plugs and shot in some more fuel cleaner. So far sounds much better. Getting lots of gas in the oil. Sure disappointed with John Deere. ....

Our Gator had issue with not wanting to idle and used Sea Foam with poor results. Had to have the carb removed and cleaned. No idea on the squealing. ....
