Gas and evaporation.

Yesterday afternoon I poured a few ounces of gas (lawn mower ethanol gas) i n a little round clean tuna fish can. To simulate a carburetor butterfly va lve I put the bottom of a tuna fish can on top of the can with gas in it, c losing off some of the air. (carburetor butterfly valves do not close air t ight) I just now checked it, most of the gas has evaporated out of there, p robally that ethanol alcohol too. I think now I am going to fill the carbur etor bowl in my 1948 Willys Jeep and see what happens. Metinks that is what happens to the carburetor bowl gas in my 1983 Dodge van, because I don't d rive it often enough to keep the carburetor bowl full of gas. T'is.

Gasoline evaporate leaves a sticky, gummy, cummulative residue that given a sufficient volume, clogges orifices.

The above poseur couldn't begin to pour piss out of a boot with instructions on the heel nor locate his own ass with a map, mirror and detailed video instructions.

I always add some Stabil to my lawn mower gas and gas in my van. At least t wice each year with the engine running and warmed up I spray a can of Gumou t carburetor cleaner through the carburetor. There is a Pure gas station ab out nine miles from me. They claim their gas is nonethanol gas. I think I w ill start filling up there.

My Corvair was the same way if I didn't drive it for longer periods. I just pumped the hell out of the pedal and she would eventually start.

That's exactly what happens.

Some evaporates, but if it empties quickly, there might be leaking lead plugs at the bottom of the float bowl. Some GM cars had an issue with that, but they would be dry in a matter of days.

Which seems to clean out more easily under pressure from a fuel injection pump than less than a foot of head.

If you piss in a boot and leave it outside during the winter, it is hard (pun intended) to pour it out later.

No leaking plugs in my little tuna fish cans. Lizard Lick Towing,, have you seen that thing made from cans on the wall in the office there? I want to make one like it to hang on my wall.

Consider replacing the mechanical fuel pump with an electric. I did this on a 1958 Dodge Power Wagon that sat a lot. Turn key on for a few seconds, let the pump fill the bowl, starts up on first turn.

Thanks, I will think about replacing the mechanical pump with an electric p ump. Older cars and trucks 'leak' gas via the gas tanks/caps and whatever. Modern day cars and trucks have evaporative emission control systems on the m.

I should do that with my 66 Datsun roadster. If it sits I have to do a lot of cranking before it starts.

With a mechanical fuel pump, a small splash of gasoline or ether in the air cleaner does the same thing with much less trouble.

Whenever I get ready to go shopping I always open the hood and check the oi l and other stuff. Next time I will squirt some starting fluid through the air filter horn and see if that helps. I will buy some small diameter coppe r tubing and flare one end with my flaring tool for a little funnel I have here. I still want to try out the copper tube 'trick' for putting some gas in the carburetor bowl. Who knows? It just might work OK. It is kind of har d to remove the engine hood cover due to a close fit between the two front seats in my van.
