idle too high after pump adjustment

[KMUNCASTER]

hey gang... . I installed my ol' Smoky fuel pin, 4" exhaust and cranked the fuel screw in a couple turns, and the smoke screw down a few... . wow !!! What have I been missing all along... . holy smokes, (no pun intended), this thing works amazing now... . fun to drive, sounds so much better... I was like a kid with a new toy... Oo.



only trouble is, even with the idle screw backed right out, it's idling a touch too high for my liking. Do I have the fuel screw in too far ? I guess I'll have to play with it.



EGT's are good, thanks to the big pipes, boost is up around 25lbs at WOT... . seems to be working nice, makes a nice black cloud at a punch of the throttle... . :-laf



poor old slushbox is gonna take a beating I'm afraid... .

Is your throttle lever hitting the idle screw? You may have to adjust the throttle rod linkage to get it to idle, or re-clock your throttle shaft.



Increase in idle is normal after turning up the full fuel screw.

nope, not hitting, I'll look at...

that tonite..... you are right, I can reclock it... . see how simple it is when someone tells ya what to do ? :-laf

dpuckett, when you say re-clock the throttle shaft that the shaft that turns when the throttle is applied?

Yes, there are tick marks around the hole in the pump that the shaft goes in to, and a slot on the tip of the shaft for lining it up. Be very careful when adjusting this, it's real easy to lose your spot with all the little parts you have to line up there. If you go too far in the direction of reducing your idle, you can actually get it to a point where it slows the motor down when you hit the accelerator. This means you went past the dead center for where the governor spring attaches to the shaft inside the pump. Go back a notch at a time until you find the idle you like, but the motor still speeds up when you first start pressing the accelerator.
