My starting problem that caused me to be 2 1/2 hours late to work yesterday, and late today, I think lies in my carb. I need pics of someone's edelbrock on the car, I want to see how the vacuum lines are hooked up and everything. I have a line going from the big port on the front in the center of the carb to the pcv valve. Is this right? There is a port on the back that is plugged up, should the line to the pcv go to it instead, and the one in the front be capped off? The hose from the dist. vacuum advance is going to the small port on the front passenger side of the carb, while the small port on the front drivers side is capped off. When I had an actual vacuum hose on the front port to the pcv valve, while the car was running, it would collapse, so I replaced it with a fuel hose. Can someone help me out here? ------------------

Sounds like all the hoses are in the right place.The PCV should go to the big port in the center front.The rear port is for power brake booster.Make sure your PCV valve is still good,they are cheap to replace.  Why do you think its the carb. SCOOP ------------------

If all else fails, get a BFH and make the appropriate adjustments, then order a Holley. 
(j/k) Seriously, why DO yo uthink it's the carb?

On my 65 with a 302 HO I had the large port in the front capped and the rear one for the pvc. It made sense to me to use that port as the original PVC hose was almost a perfect fit. Dist vac was same as yours. The engine is out of car now but it performed well with the setup I had and never once quit. There is provision on intakes for the power brake vac at the rear. not into the carb. The modulator hookup was at the rear on a Shelby intake. Car did not have power brakes. I was running a 500CFM Edelcrock.

my brake booster runs of the manifold port at the rear of the intake manifold. Never put a vacuum gage on it to find out what its pulling but my drum brakes with the booster work nicely. My rearmost carb port goes to the PCV (but i run a two barrel OEM carb).Maybe you can describe the problem with starting the car in more detail to us. have you looked at the spark plugs to see if it runs rich or lean..? i didnt see your other threads on the problem. does it idle good when you eventually start the car? sounds like the vacuum lines are correct anyway. I would be looking at ignition first then carb, but you sound sure its the carb.

It's the ignition switch I believe. I ran a jumper wire from the batt. to the coil and it started every time, so then I just put a switch in the jumper wire to make it easier until I replace the ignition switch. I do think my pcv/ vacuum lines are switched. I'm about to got put the pcv in the back and cap off the front, because it runs better with the front big port capped off. ------------------

Do you have a breather on the other valvecover? You know the PCV is more or less a big vacuum leak. If you have a open breather, try a closed oil filler "Plug" on that valvecover so that the PCV can't draw in air from the breather.
