In Reply to: 641 - gas in oil (again) posted by Mike in Michigan on July 25, 2018 at 18:14:50:
Thanks for all the tips guys. It took a while for the gas to appear in the oil, but I have been living in the city with the tractor in the garage only starting once a month or two.
Hopefully I will be able to find a quality replacement shut off valve. Let me know if there is anything unusual with replacing the shut off. Could the consistent problems with the carb/float/gas-in-oil also be caused by dirt in the gas tank?
Is there anyway to clean the tank in-place? I'd rather not remove the tank if possible and do it in conjunction with the shut off valve.
