Fred and Ultra Dog,
Does the AS&M and the LPE/Accel have the IAC port opened to the main plenum like this?

I had asked this in a post about all the other aftermarket TB's but no one ever said where these 2 brands did or not.

 

I don't have the slightest idea what the AS&M or Accel/LPE have in the way of idle passages. But then I've used both the BBK and Holley with no idle problems, so I never even looked to see what they have or don't have.

 

Can't recall specifically. Call AS&M directly.

 

Ok, today I decided the pedal was a little too stiff, so I took the TB off and made another mod.
Since it originally only had 3 holes to adjust spring tension, and it was on the last one, and winding the spring one full turn made the pedal too stiff, I drilled 2 more adjustment holes exactly 1/2 turn around from the first hole, which put the spring leg right in front of the stop screw, so I added one more directly behind the stop screw, but putting the spring in the front hole is working perfectly and the pedal is not stiff either...
Here's 2 pics of the extra adjust holes I added.
In the first pic, the holes on the left (at the bottom of the TB) are the original ones, the ones on the right (top of TB) are the ones I added with the spring installed in the one in front of the stop screw.



Now the Holley TB works beautifully

 

BBK has the same problem. I have a 58mm BBK. It started giving me that problem the same day I installed it. It went away for a month, now its back. It sticks and keeps me reved to about 2500RPM's until I smash the gas. Im gonna increase the spring load and hope that works. What bothers me is that its perfectly fine with the engine off.

 

put some oil on the spring and around the tb blades and break it in mine works just fine..
