Turnpike Boy,
Yes I am coming to the revolution on the 7th. I am really looking forward to meeting you and others there.
Demon Tech told me to use the secondary idle screw more to help stumble, and it worked. I realize that all you are doing is exposing more of the idle transfer slot. I didn't know about the effect it would have on the idle circuits. It helped me though, and when I ran the car on the chassis Dyno the A / F at idle was was 13.97. I was told 14 is about perfect. My A/F graph was pretty flat, but a little lean high peaking at 14.1. Hence the jet change. I haven't run it since then to be sure the lean condition was corrected. My idle mixture screws seem to be set at a relatively normal location.
Is your carb installed directly on the intake or do you have some type of plate between? Performer intakes are notorious for have trouble sealing properly with carb to intake with one gasket.
On the sbc I added a cheap Mr. Gasket 1/8" steel plate in between. The 302 utilizes a solid chrome plate between which also is the throttle linkage mounting point. Just a thought.
A comment on Roscoe's 1-1 linkage!
What he forgot to mention is that he is running AFR Heads, which I am sure are flowing alot more, I mean alot more air than ours. I doubt my GT40X heads would support that set up without problems.
If you are still experiancing problems when you come to the revolution, we can always distract Roscoe for awhile and exchange your demon for his!!! A couple bucks to a few Hooter Girls from King of Prussia would probally work. Of couse we will use new gaskets, we wouldn't want to take advantage of a fellow Cobra Owner!
