Yukonboat, you have another option, but it might not be to your liking.

Since the likely issue you have is ethanol in gasoline (I prefer it in martinis), remove the ethanol from the gas. Google it. I have been doing it for what seems like 10 years now.

Quick summary of what is required.

* Get 93 octane gas
* get a bunch of PET juice jugs, like quart size.
Time to trust me on this
* put an inch of water in the juice jug, fill the rest of the way with gas.
* shake like crazy (ethanol is in solution in gasoline but bonds with water, SCIENCE!)
* let it set for a day
* CAREFULLY decant the gas from the phase separated mixture at the bottom.
* CAREFULLY decant it again, looking for the water "marbles" at the bottom.

What remains is about 90 octane gas, sans ethanol. You will know that the ethanol has been removed by the fact that the level of water (really no longer water) in the bottom of the shake jug has increased in size.

Remember, you are working with an incredibly volatile substance and respect for same is required.

By the way, you will get something like a 10% gain in power as ethanol is basically a filler compared to gasoline. This is equivalent to buying gas before it was polluted by Washington and the corn lobby. Still preferable over MTBE, though. Your 18hp Kiekauffer (sp?) Mercury will love you for it.

Like to hear from you. Looks like you are new to the site from a membership standpoint.
