Correction to my comment about losing 10% of power, apparently this is
no longer the case with the latest conversion mod:
www.propane-generators.com/dedicated_kits.htm "This type of conversion
will produce FULL power because the carburetor is now delivering fuel at
the exact location that was engineered for the delivery of gasoline to
the engine air stream.

It happens that propane, as well as both alcohols, methanol and
ethanol, have an octane rating of 100. There is no reason not to
expect better efficiency and more power, compared to gasoline.The
carburetor designer's job is easier. You can realistically expect to
get the same near ideal mixture to all the cylinders. The perfect
fuel, actually.Historically, propane has been cheaper and there were
engines around that could use the octane..
