Is that the car you have Woody??? The 1.600 Venturi? I've heard the same as PRH but never tuned one yet.
I agree...get an O2 sensor and look at the plugs. Probably start where you are and keep damn meticulous notes so if you get lost you can see where you've been.
Keep us posted. This should be fun.
Wait a minute...92's front and rear??? Is there a power valve in both ends? If so, I'd open the throttle 1:1 and tune it from there.
I'm considering doing that on my carb. I've done 1:1 before and always loved it.
