Re: no rough idle



Idle quality (hunting) is directly affected by vacuum leaks, a 
breakdown of the secondary ignition system dirty or missfiring 
injecters, and an out of balance cylinder ie: low compression, burnt 
valve etc. You have to remember that the engine operates like a wheel, 
it keeps going around so if 1 cylinder's output is lower (or higher) 
than the others whenever it's turn comes around it will fire a little 
differently than the others causing the engine to speed up or slow 
down then the idle system tries to correct it but it can't react fast 
enough to cancel out the effects of 1 cylinder so it over or 
undershoots resulting in "hunting". A properly tuned motor when warm 
will hardly hunt at all. A cold motor will hunt a little initially but 
quickly calm down as the cold start valve shuts off. To improve gas 
mileage you might need a tune-up and or a mixture adjustment. The 
mixture screw is a very sensitive adjustment so if a 1/2 turn isn't 
making a difference you probably have a vacuum leak somewhere (which 
might account for your bad gas mileage)
