High Idle
Guys..
I have this 82 Liquifire running, however the idle just will not setting down, its consistently at 3000 or more and will climb to 4000. I am running it with the air box off...never had this problem before. I just put new crank seals in it. The only thing that is eating at me it the timing mark on the stator, I set it exactly where it was when I took it apart and that was a little advanced or counterclockwise of the mark or seam on the case halves. I have the idle screws backed out so far they could fall out of the carbs.
I am thinking I have an air leak...
open for thoughts

Re: High Idle
How are the cables set just on top of the carbs?
Many new and used parts available, I ship anywhere. Thanks everyone.

Re: High Idle
I guess I could back them all the way off and go from there, never thought of that till now. Slides are closed enough in my opinion, but...

Re: High Idle
Are the slides bottomed out inside the carb?

Re: High Idle
Recently had the same problem with the Cross Country. Problem was slides were too high. Also, check throttle cable routing to make certain that's not the problem.

Re: High Idle
A really quick check to make sure the cables aren't too tight and the slides are bottoming out is just to give the throttle a quick flip when the engine isn't running. When the slides hit the idle adjustment screw there is a real metalic click you won't hear if the cables are bottoming out first.

Re: High Idle
I know that metallic knock and I can hear it on both carbs, screws backed out no knock. I am very aware of the cable routing with the dash up/dash down, it doesnt matter, pulled on the choke plungers thinking one may have been hanging up, no such thing. I will take the adjustment out of the cables and start there. You know, I was trying to feel the slides move up and down with the idle adjustment screws and wasnt really satisfied with the performance, I couldnt really feel the slides moving in any direction. I even pulled the slides out looking for issues with the springs. I will be taking the adjustment out of the cables and start there. I will report my findings.
