Its been a long slow process getting the old girl back down to earth but today I finally did it! I'll be taking it in after the new year for a respray. Now that I have an LM-1 hooked up and can see what I have driving around with I need some help. At idle and low-mid range the AFR is right at 13.5. At WOT it drops back into the mid to upper 12's after I richened it up with the spring loaded screw atop the intake. My question is, shouldn't the low end AFR be richer after I turned it clockwise? Also, is there a limit to how far I can turn the adjustment screw before it has no more affect or do I bottom out and can turn it no further?
On a different note, the clutch was stuck and would not engage/disengage when I got it down to the deck. I shut it off and put it into reverse and then started it up and its been fine ever since. Is there something that I might want to check or is this something that is common?
I appreciate any help you guys can give me.

You are right, clockwise richens and cc leans it out. Regarding the clutch stuck to the flywheel, you should check that your driving the car on a regular basis ... ask me how I know.

As for the clutch, after a long period of no driving, they can actually rust to the flywheel, probably what you encountered.
