There was some question about how the rate of propane flow was
regulated in propane-converted vehicles.

If I remember correctly what the mechanic told me, there is a
vacuum-operated valve that regulates the amount of propane pumped
into the carburetor according to the amount of vacuum. Since instances
of greatest power demand produce the least vacuum, this valve must 
operate inversely with the amount of engine vacuum, sending the most
propane when there is least vacuum. Of course this means that if you
leave the ignition on without the engine running, the thing will spill
propane gas all over your engine compartment. Therefore, they installed
a vacuum switch that turns off the propane flow when it senses two full
seconds of absolute zero vacuum.

BTW, if you hate flies, you will hate propane. The stuff they put in
propane to make it stink (so you can detect leaks) will attract every
fly from a mile radius if you have any leaks. Flies LOVE this stuff.
When the service station fills your tank, some propane leaks out,
and here come the flies. I had seriously thought about developing a
propane-powered fly trap.
