I agree with Wasp, that is funny.

Back in the Seventies, I was into dirt track racing. In some locations, racers would use alcohol instead of gasoline, by (1) pressurizing the tank to feed fuel fast enough, (2) using 3 Strombergs, to distribute the fuel better through the intake, and (3) drilling out the jets, to provide the higher flow rate necessary. A side benefit was the reduced cooling requirements - you could use a smaller radiator, and put baffles in front of it to keep the fins from getting plugged or bent.

The Eighties saw the introduction of butyl rubber carburetor floats (that would absorb water, I understand, and became too heavy to float in gasoline or gasohol) and (in the case of Chrysler) some accelerator pump materials that would shrink (making the engine stumble on acceleration, like when turning left in front of traffic...). And one of those commercial engine manufacturers (Kohler?) started using a float that was like a ping-pong ball, it would swell up & stick in the float bowl when used with gasohol.

Memories of those experiences from the Eighties may be having an influence on some of the comments here, but I don't recall as WalBro was ever on the list.

Best wishes,
