I am trying everything from replacing the carb and distributor, Whats happening is this:
When I try to start it in the cold mornings it takes about 20 mins before it will start and stay on for a few seconds and then I have to crank it quite a few more times to get it fired up to where it will run without shutting off. I am putting a 750 holley Electric choke on it and have a MSD Distributor on it now. Is there anything else to help this start up problem. It's tuned up good and runs Excellent when it's ran for about 20 mins straight. Is there anything that can help any parts I am missing that might cause this, any parts I can put on, take off, or anything. I dont want to put Fuel Injection on it cause I can get more power out of my Carb. Anything would help. Thanks

Are both the cold idle speed screw and choke correctly adjusted? Another thing that helps hard starting cars to start easier is to retard the timing a bit. Unfortunately, that will drecrease your power once the car is running.

Unless of course you have a manual ignition timing lever inside the car by the driver like the old ford model T's and models A's had. :D

It sounds like your choke pulloff-Safety First-block the choke plate open with a screwdriver, pump acc. Pedal 2x then fire it up-now tell me what happened

A good tune-up is you don't have to touch the gas pedal, just turn the key and that's it. Every system will come in play when its done right.

20mins is just the warm-up time for the engine-anything less than that is calling for a future problem.

Alrighty sorry to take so long to reply, I finally got it running and then decided to change my Carb. Now I prepared the carb and my Brother took off the Old Carb Before I got a chance to mark or even memorize anything. Now i've got a problem small but yet it hinders me. I've installed all the vacumm hoses but now my throttle bracket I can not seem to make it fit. Would it be my Carb or am I overlooking something, I will have pictures soon but I need some pictures of how this thing bolts on as I am stupid and when you all start saying all these names I have no clue. I am only a beginner and trying. Again I have installed the Carb after like 2 Hours and now without even seeing it before my Dumb@$$ brother took it off I have managed to successfully hook up everything else but my Throttle Cable and Bracket. Does it mount to the intake manifold or Carb or both or what. Please someone help me.

I have been looking at it and I believe I have to change my throttle cable, bracket, and spring. The old one bolted to the Carb and the new Carb has no were to bolt to. I will call The company and see if they have all that to fit my camaro and carb size.
Thanks for the reply. You guys are awesome
