It seems like the fuel might be draining out of the carb when the car (1955 Thunderbird 292 stock carb and fuel pump)  is not started for a few days.   I don't want to install an electric fuel pump.   I ordered a check valve that mounts to the fuel pump.   Has anyone used the check valve?   Any other possible fixes besides the valve and electric pump?

"Interestingly enough, I recently posted this video https://youtu.be/W88wjkI7UJE. (Aviation gasoline in my 1955 Ford Fairlane, 292 Y Block, Summit Carburetor, mechanical fuel pump)".

Now that is an excellent write-up!

More informative than most professionally written tech articles ...

I enjoyed the reverends video on aviation fuel.  I noticed the 2 MPG increase in fuel economy.  Is that same increase gained is you use regular unleaded non-ethanol fuel such as available in most states?  I know this fuel is available in Nevada at selected stations.  I would be curious to know if there is any advantage of traveling there and buying a 100 gallons to use in my classic cars.  I have always been told that using a higher octane fuel in a car that is not high compression is a waste of money.  So I am wondering if just the elimination of the ethanol is a factor in increased fuel economy?
