I'm in the great white north (Alberta, Canada) and am at the point with my fairlane build where I'm in the deciding stages of what to do about a choke. The engine is a ford FE with dual holley 600's, no electric chokes. I've never run a dual quad car before, what are you suggestions on running a manual choke? Obviously not planning on running the car in extreme cold, but should I be concerned with running a manual choke cable to one or both of the carbs?
if you have progressive linkage, run a choke cable to the primary carb. If you are running them 1:1, then both need a cable. you could make a two to one lever thing to fit under the dash, so one knob pulls two cables. Or just keep the idle a tad rich, and warm it up before you drive.
Just run a cable to your primary carb chock and delete the choke on the secondary unless you are running them straight up in which case run two cables or a linkage from one chock to the next. if you get a proper manual choke kit you will still have a high speed idle option.
Hit up jay browns fe power site for advice - a super group of guys - many say its hard to get to #1850 600 holleys to run right on a stock fe manifold.....most run the holley re-issue BJ/BK carbs - there are other FE forums, but Jay's is the best
LOL I have run more then my share of cars without a choke summer and winter although seldom below -15Farenheight.
I ran my 55 for years with the blower, with progressive Holley 650s, and a choke on the rear carb. Then when I put the blower on the Chevy II, I run Carters straight linkage, no choke, works fine.
One back fire cold and you will be replacing the power valves. Use one choke either carb, it will give you enough fuel to run cold.
