Admittedly, I do not know a lot about this stuff but when I had a Suzuki 6 hp/4 stroke I had all kinds of problems with gumming up the carb, the fuel lines, etc. The ethanol literally eats away at the rubber fuel line of the Suzuki and peeled away "gunk" from the inside wall of the gas tank
Yikes
I then cleaned out everything and started using ethanol FREE gas I got at a local marina. It cost a little more than regular 10 ethanol gas (about $.90 cents more) but it solved the problem. Getting the ethanol free gas was easy.
The suggestion about turning off the gas line and running the engine dry is a good suggestion regardless of fuel being used.
I recently posted a website on this thread that has a list of gas stations, marinas, etc. that sell ethanol free gas. I am confident most of us live near one of these locations. The list is current as of 01 July 2019. They have a gas station listed in Miami that just opened 2 weeks ago.
I am wondering why folks are talking about trying to get aviation fuel, 100LL AV gas, Tru-Mix, etc. I am sure they are all very good fuels but simple ethanol free gas works well in most, if not all, O/Bs and is a lot less than $21/gallon (doubles yikes
) for aviation type fuel.
