My 67 sedan has a 355, alum. heads,air gap intake, 750 eld. and a comp solid cam .520 int., .540 exh. The problem is when i first start it , it dosn't want to idle until it's warmed up completly, then it seems fine. Any one else experience this ? I've seen some pretty wild motors on and off the track and they seem fine idleing almost immediatly. Thanks Everyone

i'm guessing ,,

i'm guessing your carb has no choke , and what your experiencing is totally normal. You could put the choke linkage back on the carb and not instal the choke plate but connect it to a mechanical choke cable set up. This would allow the fast idle set up to be used even if your choke tower is removed.

You could also get the solenoid and bracket to come up with a fast idle system thats available from holley

Your right I don't have a choke, since I only drive it in warm weather (live in MI.) I never hooked up the manual choke. I safety wired the plate closed to avoid it from closing while driving. I really appreciate the help thanks.

MI with no choke? i have mine hooked up and use it daily, some engine need it some dont, id hook it up anyway, you can also use it as a tool to tune your carb.

when cold the engine needs more fuel to run till it heats up. Is the manifold crossover plugged off? this will ad the the warm up time, which is okay. with no choke your right foot is gonna be the choke till it warms up. Not a big deal at all. Just your carb runs leaner at cold start up than some. Wouldn't even worry about it. You could always hook up the choke or convert to an electric choke.

Not sure about the manifold crossover, It' a Edelbrock RPM Air Gap, Thanks again for all the help.
