Default got the 40. here's the 1st question of MANY.

Although the 40 I just picked up has been 'restified' quite nicely...it needs a little TLC after getting none for a last several years. I'll post up a nice poser driveway pic later...but I GOTTA FIX THIS SUPER HIGH IDLE.

I have a super high idle and when going through the process I normally do - set the fast idle, then set the 'regular' idle - the adj. screws don't effect the idle at all.

Tonight I'm going to check to see if the secondary is stuck open. Is there anything else I should check? Like, are there return springs or something I need to check out?

Thanks!!!

It was in the 40's section FAQ titled "Updated Carb tech"

Default thanks Ken, this helps...but...

I can't get the idle to change at all using those adj. screws. I can turn'em all the way each way, and it doesn't do anything to the idle. I can't get the sucker to idle below what sounds like "ludicrous idle-speed". I don't have a tach, but it sounds like 1200+rpm. OH, the only thing I can do to effect the idle speed is lifting up on the skinny-pedal.

Let me know if you think I'm on the right track for tonight's fun in driveway.

1. clean carb
2. Check if secondary is stuck
3. test for vac leaks using procedure in link provided by Romer
4. I don't have timing gun, tach, nor vac guage...so that stuff is outta the question.

Question: It's got headers, anything special I should check given that?

I'd like to get to the point where I can at least change the idle speed using the adj. screws. Right now, she just ROARS, really loud.

thanks again!

first thing: buy lots of carb cleaner.
second thing: spray said carb cleaner around carb and vacuum lines
third thing: fix air leak....

If the pedal affects it, you need a return spring. The engine is probably sucking the butterflies open.

x2 on what Mike said...If I understand you right when you lift on the pedal the RPM drops down to normal, or what sounds like more normal? Then when you let the pedal go the idle goes back up?

Maybe the spring is 'sprung' or popped off or?? Remember I am mechanically challenged but this seems to make a lot of sense and would seem to coincide with the adjustment screws having no affect.

the spring is on the carb. It is listed in the SOR link above but kinda hard to see. The spring is not on the pedal itself even though some have one there as well.
