Reply to "cold start problem"

Sounds like a choke issue.

I have a Holley on the car. I converted it to an electronic choke. I found that the universal Holley choke thermostat opened way to fast for this engine and the car would start immediately but stall within a minute or so.

Through experimentation I found that the choke thermostat used on the last 4v carburetored 84 or 85 Mustang GT with the 302 works really well. It alters the rate at which the choke opens (opens slower) and therefore kept the car from stalling.

You can get them across the counter in a Standard brand and they aren't expensive. About $28 as I recall.

You will need to alter the mount to the carb, "a little" since the collar that holds it to the carb grounds the thermostat directly to the carb, so this isn't a complete simple bolt on, but it isn't difficult.

Other then that, you could try Pantera Electronics Engine Controller, which lets you alter the rate at which YOUR choke opens, provided it is electronic, that is.

Best...Happy New Year to all. See you next year?
