Gas Adjustments

Posted by:

PURPOSE
The gas adjustments are calibrated best by the use of a Dynometer as this will provide the most accurate measure of torque thus maximising the fuel economy.  There are basically three adjustments to be made on any gas system.  They are idle, cruising and full throttle.  The idle should be the only one requiring adjustment and the full throttle and cruising adjustment are best performed on a Dyno by a qualified gas fitter, preferably every 10,000Kms.

THINGS TO LOOK FOR
Heavy fuel consumption is one indication that the gas system requires adjustment.  Most gas vehicles can be running too rich.  Another indication is a lack of power.  These two problems are difficult to rectify but if your engine idles rough check that all the rubber ducting is in order and well secured.  A sign for running rich or running rough is a dirty air cleaner.  Be sure that it is not blocked or built up with dirt.  After checking all these components, the last thing to do is adjusting the idle, but remember where you started as this may make no difference so if it doesn’t return the adjustment, screw to the original position

IS IT EXPENSIVE TO REPAIR?
A good Dyno tune may cost around $95.00 and a good Dyno tune should improve your vehicle’s performance and economy.

TEMPORARY REPAIR AND LONG TERM REPLACEMENT
There is only one temporary adjustment and that is the idle.  Other than that, the adjustments will affect the vehicle’s performance and the emissions entering the atmosphere.
