You will never get it to run smoothly and at the correct speed unless you have complete control over the engine's air. You must fix all the vacuum leaks first before you get the engine to idle correctly. The throttle arm MUST be stopped by the set screw hitting the plate. Then adjust the other set screw to activate the idle switch. The idle switch MUST NOT take the full force of the throtttle linkage or it will break. You might have to clean the throttle plates and air passages especially if there was a lot of leakage which brings in dirt. The throttle plates should be stopped by the set screw before they hit the sides of the air passages hard but they should be fully closed also. Then you can adjust the idle micro so it clicks and then just a little bit more. The entire throttle linkage should move smoothly without sticking and the springs should return everything to idle every time. There should also not be much play in the linkage so you have the maximum amount of control. You can also check that you get full control ie: have someone hold the accelerator pedal all the way down. While they hold it there you look to make sure the throtle plates fully open and the throttle spool activates the W.O.T. micro. Sometimes the carpets or floor mats prevent this and sometimes the pedal linkage bends so you don't get the full travel. David Teitelbaum vin 10757 --- In dmcnews@xxxxxxxxxxxxxxx, "K.
