Ethanol
Let's talk a little about using fuel with ethanol. I think just about all the fuel available in my area contains ethanol. I've had my '72 for almost 2 weeks and I have run maybe 25 gallons of 87-octane fuel with ethanol through it so far. My brother-in-law has a '66 and he warned me about fuel with ethanol, saying it caused him to have to rebuild his carburetor. He also told me about a place here in my town to get ethanol-free gas without having to pay a huge price. So that got me to thinking about it. I found a website http://pure-gas.org that lists places to get ethanol-free gas. I guess my question is, what does everyone here do? Do you use ethanol-free gas, or is there some additive I can put in gas with ethanol to neutralize the bad effects? I'm interested to hear some "expert" commentary!
THANKS in advance!!!

Ethanol is hygroscopic meaning it attracts water, it will attract water out of the very air itself, it will also clean out your fuel lines, etc which may clog your fuel filter. When ethanol and water mix with other contaminants it becomes like a jelly and if you leave your vehicle and don't start it for months it will become like plastic in the carb, etc.

I use 87 gas which "may contain up to 10% ethanol". Ethanol-free gas is available here in Vancouver but only as 94 octane which is even more expensive. So far no problems with the AFB carb.

I can't remember where I read about it but there were some plastic components in older carbs that were not compatible with ethanol but if you rebuild with a new kit it should not be that big of a deal. Leaving any fuel in a carb for months is a bad idea imho.....

I started using the ethanol additive for my blower and weed eater 2 years ago and haven't had any issues since. I had to do a number on my blower due to that crap.....thought I heard taps in the distance....

I own a weed-eater, 2 chainsaws (McCulloch and Stihl), a lawn mower, a snowblower, a 1998 Plymouth Voyager (wife drives it), a 1999 Plymouth Grand Voyager, and Frodo, my 1969 F250 CS.
None of them get ethanol. I may pay 25c more per gallon, but when you factor in the loss of gas mileage versus the price differential, I'm actually coming out ahead of the game.

You are stuck, pal, like all the rest of us. We burn corn with 3/4 of the energy value of gasoline. We ship cleaner air to India and China and their crap blows back to us unimpeded with no change in the grand scheme of things.

I run Chevron's 87 <10% Ethanol with no problems in my bumpside. No issues. On my dirtbike though I always run the 94... but that thing has 13:1 compression.

Back in the day when that gas was introduced I sold more carb kits and mechanical fuel pumps that Carter has little pills. The old rubber diaghrams,seals,etc were ruined by the new Corn gas. I would assume these have already been changed in your Bump. Corn gas has been out for a whole lot of years now. Note. A relative of a neighbor of mine still lives in back woods Virginia. He burns home brewed Moonshine to power his house's generator. Which is not necessarily made with corn.

Ethanol doesn't keep very well
I've been told that ethanol gas doesn't keep very well. In Canada there is no alcohol additive in premium gas. I just keep premium in my jerry cans for use in all my mowers, weedwacker, tiller, etc.
