Also if you haven't already, give it an oil change, also air and oil filter change too

Not sure on the plumbing though

Post by: murph on April 19, 2006, 18:48:38: If you present it on gas it should be tested on gas, mine runs on lpg all the time, even on start up so they had no choice.

picture shows how the vacuum pipes go, the one between the pump and dizzy is blanked off on mine. the other goes to the inlet manifold
