Thanks Doug, appreciate all the info - I'm interested by everyone's 'eye-stinging' comments as that has been my experience too. My last effort to reduce idle richness had negative overall effects so I'm going to change it back to your stated #s and ignore all the sting & fumes. That said I might try F5s instead of the 7s. Chokes are 37mm, certainly don't want anything larger given the type of (too infrequent!) real use the car gets.
Tom, are you still running 150 mains/210 air like in older days? Engine looks great btw! Regards, Nate
