It is not corn gas. The corn is used to produce alcohol that is added to the gasoline. In days of old, people would add dry gas to the car tank in winter. Dry gas is/was alcohol. The reason it worked was that alcohol mixes readily with both gasoline and water.
Part of the problem is that alcohol in the fuel will also absorb water from the air if it sits around as in people who do not use a golf cart, an airplane regularly.
AVIATION FUEL IS LEADED FUEL AND IS HIGHER OCTANE THAT THE 89 SOLD AS REGULAR GAS. The lead lubricates the valves and as in older outboard engines, the gaskets may not be alcohol proof.
Unlike the way many people maintain their cars, golf carts etc, a plane has a service record. You must do repairs before they fail. You must have a record of service or it will not be flight worthy.
