Vaporizing gas fix

I'm not sure if this topic has been discussed before so here goes.
I was having trouble restarting our '52 Mayfair on hot days. I have an electric fuel pump so I don't think the issue was vapor lock, but rather the gas vaporizing in the carborator. When the air cleaner was removed you could actually observe the gas "boiling" right in the chamber.
I friend auggested adding about a gallon of diesel fuel to every 10 gallons of gas. The theory was that the diesel would lower the volitization point of the gas so it wouldn't "boil".
Does this make any sense to you engineers?
It seems to be working so far. We drove 600 miles on a tour in hot weather and she never failed us once! And it doesn't seem to smoke out of the pipe any more than it ever did!
