Compression 140-160 1971

I'm currently of the opinion that I have to change to smaller pilot jets. A small constant manifold leak improves my idle markedly. I'm running my slide stop screws at max...not for more fuel...but for more air!

I already have a return spring, and it helps a lot...but you have to find an idle configuration which has the slides resting on the slide stop screws ONLY. Any dependence on original idle stop plate will cause inconsistency. Difficulty here also (as you've mentioned) is torsion between the two slides, if one slide is set higher than the other for manifold balance...making one stick.

I have a usable setup, with a consistent 1K idle running at 11.8 to 12.8 afr...still lumpy, and with a little lag on jackrabbit starts

I had a short conversation with "planetman" today...nobody considers these "plug and play" retrofits
