Hey Guys,
Some good advise as always!
The only thing that complicates the matter is sparks never mentioned the brand of carburator he is using.
If he has a Demon,the tuning is sooo much easiler, as we all know! But!!!
Sparks,
If it is a Holley this may help also.

I hope you get your problem solved. I have been dicking around with one myself for a couple of weeks now myself. Good luck!
