You were absolutely correct. I was adjusting the damn air mixure screws and
not the idle screws. I finally figured out what the hell was going on.
Fortunately for me, a neighbor who restores old Mercedes stopped by and told
me I had to adjust the Unisyn to get a reading (as you said) and voila !!
Now the only problem is no matter what I do I can't get both carbs to get the
same reading. The rear carb, when covered by the Unisyn, causes the motor to
stumble a bit. I have the air mixture screw baily opened on that one. The
front carb barely gets a reading practically no matter what the heck I do. I
have it opened SEVERAL turns. Does this mean that my carbs are essentially
toast do you think? Despite the fact I probably have the SU's nowhere near
tuned, I went out for a test spin and WWWWWWWOOOOOOOOOWWWWWW !!!!! The car
absolutely hums !! No more stall at low RPM's, and if I punch the throttle
there is INSTANT response. Major improvement. Thanks again for such a fine
product, the excellent instructions, and the follow up advice. The wife and
I will heading out to dinner in the sunset tonight and I may be scaring the
hell out of here with my driving.
