Bob,
Best thing is to siphon all suspect gas out of the tank BEFORE it does
any more damage and BEFORE adding any good gas to it. After you get out as
much as you can, disconnect the fuel line from the carb, add fresh gas with
isopropyl alcohol (isopropanol) to absorb the water condensate and an carb
cleaner (like Chevron Techron) and flush out the lines and the pump until the gas
flows clean. Then rehook up the line to the carb and try running the engine
again.
In YOUR case you'd better siphon out ALL the gas (old + new) and start
over.
By the way, what do you mean by methyl hydrate? Do you mean methyl
alcohol (methanol, CH3OH?) The isopropanol type of gas additive (like "IsoDri")
is much better and less corrosive.
Good luck!

Well ,perhaps some Corvair...
I have recently purchased an "elderly" boat which has sat around for a while
- like some Corvairs we have purchased.
It had about half a tank of gas of indeterminate age. I topped it up but it
is exhibiting running symptoms that make me think I have bad gas and/or
water in the gas.
I can add methyl hydrate to absorb any water but what can I do about the bad
gas? There is no practical way to drain the tank (I think they put the tank
on the floor and built the boat around it!)
Any ideas most appreciated!
Thanks,
Bob
