Just installed engine, couldnt tune idle!

[oh-la-la]

HI guys,
I just started up the engine last night everything seemed to be fine except i couldnt lower the idle. Turned the idle screw but it didnt make any different, it has about 3 1/2 counterclockwise now but still very high. Where should be the problem?
Thanks

ok then, you got her done

i'm going to suggest you look at "intake leak" topics...you're gonna want to check to see if the flange is flat, make a better intake gasket (if you haven't already), & check the carby-to-intake connection (some guys are solving this with an o-ring)...if you're revving too high it's because something's letting in a lot of air...only my opinion based on what you posted.

from a mechanical standpoint, you might want to make sure the throttle/slide is actually returning smoothly.

Thanks for you info, Ill check on the leak and try to get the o-ring. Can we get it from any hardware stores?

Throtle slide

Ya, know my engine never does slide back smooth. In fact it gets stuck a lot especially when I monkey around with the pin and clip thing it never has slid in good. I make sure I have that long grove where the cable goes in lined up with that little metal nipple stud thing. Still does not slide right. I have thought about sanding it down with fine sand paper around it ya know like the old wheel cylinders I have put oil on it though. no help. If you sand it will that be a good idea to make it slide?

Gasket

I made a gasket for The intake from automotive gasket material number 5 You can get it at an automotive store I used RTv blue silicone stuff number 1 for where the carb goes on 3. Number 4 and 2 is my old bad gasket.

The original gasket is like tissue paper. Mine was ripped. of course I do not know if it did that when I took it off or not.
