Re: [VAC] Any advice you all!!!

Most good propane shops can do that. It takes a different (but simple)
carburetor, and a couple regulators, one regulating tank pressure down
to a few inches of water column and the other to below atmospheric so it
supplies propane only to the vacuum of the venturi. For small engines it
may not require a vaporizer, but for truck size engines it does. My
standby Onan would take two 100 pound bottles to keep enough vapor to
run it at full load (5 KVA).

There is an encyclopedia of propane that I found at a big used book fair
and is in some libraries that has a chapter or two on setting up
engines.

You could do a www.google.com search on "Propane engine" and come up
with a number of web sites to look into.

Some schools run propane in their busses so their chief mechanic should
know a bit about the topic and know who does the conversions locally.
