Clean fuel tank on my EZ

Well it took some doing , but i got the tank clean. saws together and running, oils good. Drain the tanks and set it on the shelf, start looking for another saw.

I clean tanks (all kinds) by padding and strapping them to my tractors wheel/tire and just let them tumble on slow speed with something inside the tank.

Put a liquid inside, water is ok at first, put plastic bag material under the gas cap to seal the vent if using a liquid such as water, leave the cap where the liquid can be dumped and changed while the saw or tank is still strapped. Can use small amount acetone/ lacquer thinner or even gas during final tumbling. I've had to tumble some of the old McCulloch Magnesium chainsaw gas tanks that are chalky inside due to being stored dry.

Remove the bar on chainsaws. this method cleans the inside really good for small engine metal gas tanks and even large tractor tanks and vehicle gas tanks as a good cleaning before using a Red Kote sealer. Some metal small engine gas tanks will actually polish really clean inside not requiring a sealer.
Some of the larger tanks have a baffle inside and may require an additional access hole for good cleaning or adding a sealer.

I can elevate the tractor wheel, strap the tanks and go do other things while the wheel is turning/tumbling the tanks slow at engine idle. Just remove the tanks cap while still strapped in place and flush change the liquid and when the liquid appears clean the tank internally is usually clean enough.

Not a fun job but some tanks are NLA and expensive if found.
