My dad has a 67 camaro with a 250 straight six. It is all original with ALL the smog stuff still hooked up. We are having problems keeping it running. It starts not a problem, but it will not stay running. It will start, run for a second, then die. If you give it gas, it will act like it is using it up before you lift the throttle. We have thrown parts at it already, and to no avail. We have changed the points and gapped them to .019 like the book says to for new points. We have new spark plugs gapped to .035 like the book says to. We have put in a new starter solenoid out of desperation, as well as a newly rebuilt carb. We also changed the fuel filter, and adjusted the mixture settings, and idle speed settings, as well as the choke settings. We also replaced the condenser in the distributor. We adjusted the timing to what the book says to put it at. We have the air cleaner off, so we know it is getting air. We can see the fuel in the fuel filter so we know it is getting fuel. The only thing we can't see is the spark. Could it be the coil? Would that cause the car to start, and not run?
We are banging out heads against the wall and are out of patience. Any ideas?

Any help will be greatly appreciated. THANKS!!

The electronics are very straight-forward on your Camaro. Be sure to test for spark at each plug. If there's no spark, when the standard spark test is performed, I would test/replace the coil. Try this and get back to us.

Remember, point gap should be .019" at the high point of the cam lobe.

We replaced the points style distributor with a Petronix Flame thrower and changed out the coil. It seems to be fixed. We had it running once and then it happened again. So for now, it looks to be fixed. But I will update for sure in a few days. Thanks for the advice!

This seems to have fixed the problem. It idles high in the morning when it first fires up, but we are going to adjust the choke and see if that helps.

High idle cold on these old machines is normal.
That carb should have a choke cam attached and the choke pull-off should allow the choke to mechanically step up the idle during a cold start to draw fuel in at a higher rate.
Once the engine has warmed, even for just a few minutes, jazzing the gas briefly should allow the idle to step down slightly.
If you're not accustomed to carburators and how they work, especially cold, there will be a learning curve. Let me know if you want further advise regarding what to expect here.

I am some what famiiar with carbs. My daily driver has a carb'd 350 and this is my dad's car. He is planning to adjust the choke rod a little and see if that helps. Hopefully!
