Re: Idle speed blues. Still need suggestions please.

Before doing ANYTHING get a good tach on the engine so you can 
accuratly see what is going on. Don't trust the tach in the dash as it 
isn't possible to read small changes and isn't always accurate. I 
think the idle rpm is 770 plus minus 50. If it isn't it can be 
adjusted by turning the screws on the stop by throotle spool. If you 
touch one you have to adjust the other that hits the idle micro. Only 
touch these adjustments after being sure that the ignition system is 
PERFECT and the mixture is properly set and there are NO VACUUM LEAKS. 
Any of these things will affect idle speed and quality. If the engine 
is idling at 600 ? and is really smooth and doesn't stall why don't 
you just leave it alone?
