I think they switched to some other material that had some sort of chlorine compound in it. Somethink that was corrosive. If I run across the link again I'll forward it.

How are you gonna run the tubing from the seat to the air intake?

Ok I did a little checking around and it looks like there are two different formulations for mothballs, one is naphthalene and the other more common one is paradichlorobenzene. Naphthalene is basically two benzene rings hooked together by a common carbon atom. It is a dirty burning fuel because the ratio of carbon to hydrogen is high. Use too many mothballs and the engine will load up with carbon deposits. I remember we used to poke only a few mothballs per tank. Iím not sure you would want to do that now with fuel injection and catalytic converters. Even though both mothballs will burn, you donít want to use the paradichlorobenzene ones, it will form hydrochloric acid (HCI) upon combustion, not good for engine internals! Oh well, it's fun to talk about.

Rubbing alcohol

Any one ever try to add rubbing alcohol ? I saw that in a thread not too long ago. I really haven't done much testing. I cleaned out a gas can with the stuff, and added some 87 octane fuel. Engine actually seems to run better with just a cap full to a gallon.

Yeah, my dad put some rubbing alcohol in an old lawnmower. It ran great on it. Make sure you get the 90-95% stuff, not the 30% with 70% water.

My ethanol idea is progressing; I have ordered the still and boiler plans. Hopefully sometime this summer I'll be able to thumb my nose at the gas stations!

99% rubbing alcohol

Tried it today, Engine runs smoother, but seems to be burning more fuel. the mpg has gone down. In another thread a guy has been testing acetone and he says 8 oz per full tank seems to give him about 10% better mpg. I got a quart of the stuff I'll be trying it after I get a few things fixed on the truck.

On another note. I found a huge leak in my secondary tank today. Just a reminder to check those things.... hate to pay for gas that just ends up on the ground.
