Re: Anybody got the end all cure for vapor locking?

Ethanol slows the burn rate which makes the engine run hotter. That can be patched by changing carburetion which will increase fuel consumption even further.

According to a Packard service bulletin vapor lock in updraft carbureted engines takes place inside the carburetor.

The diesel fuel thing is something Model A owners have been doing for a long time. It actually provides a level of top cylinder lubrication, but also likely reduces performance. If there are air leaks in the system it helps to reduce that too.

And yes, I have gotten gaskets that are not made to pattern from reputable suppliers. It is a disappointing experience the same way as drop shipping scams on the junknet. Inspect all parts prior to assembly.
