Hard to start in the morning, running rich and slooooww...

Drove it all day today, and for the most part it runs well. I noticed the #6 plug is still getting carbon fouled, but the other plugs are a bit lean with a 52 jet. I put in a 56, but haven't had a chance to do a plug read again since. Seems to run better, though.
Currently I have a Standard blue streak cap and rotor on the distributor, and they are relatively new.
I'm still noticing a slight miss at idle, or when the motor is being held at a constant speed at low (>3000rpm) rev. I am chocking it up to the fouled #6 until I replace the plugs.

Thanks again for all your advice, driving the Valiant today was like being in a different car!

with the 56 you'll probably see a little hesitation at cruise and be in the power valve more than needed.

On lean #6 do you have power brakes? you should check the fitting, 3/8" line, and booster to make sure you dont have a leak. that would lean out just number six.

On the slight miss its a slant thing, i know of only one car that has gotten rid of it with a homebrew water injection. But somethings that will cause it are to lean or to fat, holes/cracks/leaks in the exhaust, ignition issues as well. i'll get i vid of my swinger and you can tell me if its the same thing.
