LP Fuel system (Sandard and/or
Low Emission Version)
This checklist is your guide to the most probable
causes of an engine performance complaint when
the malfunction is due to carburetion.
The troubleshooting approach is designed to
diagnose problems in vehicles that have performed
properly in the past and where time and/or wear
have created the troublesome condition.
Locating a problem in a propane engine is done in
exactly the same way as with a gasoline engine.
Consider all parts of the ignition and mechanical
systems as well as the fuel system. It is
recommended that you systematically check
potential causes of a particular complaint in every
possible area before making changes or
adjustments to the carburetion equipment.
Every possible cause of poor performance cannot
be covered, so if doing the work prescribed does
not correct the problem a more extensive checkout
and diagnosis will have to be made.
Don’t stop after replacing a failed part. Find out
what caused the part to go bad and eliminate the
cause of the failure.
