Is there an adjustment on the cable going from the gas pedal to the carb? If I gas it,it will race and I have put my toe under the gas pedal and pull it towards me. I`ve cut the spring a bit under the pedal to no avail. Thank You

Yes! There is a threaded adjustment and lock-nut at each end. But your problem sounds to me, like you need a stronger throttle return spring. Or more than one spring. Or that your cable may be "gummed-up" and in need of some lubricant. Or the carb. butterfly valves and/or shaft are sticking and need a shot of WD-40. Lastly! There is also a gas pedal "position" adjustment, way up to the top of the pedal mount(a simple bolt-stop with a lock-nut)(this might be what you are looking for). This is to help eliminate the slack/play out of the gas pedal movement in relation to the carb. butterfies opening and in turn improve on reactionary throttle reponse. I have my gas pedal stop adjusted with very, very little slack! You need some to allow for "things" getting hot and expanding around, and on the engine. As soon as I TOUCH the pedal, the throttle shaft is responding! Best of luck with it, Marlin. #5723
My car has been modified so much that I do not know what is stock any more but, here is my two cents.
First make sure the spring under the gas pedal is under tension.
Second there are two adjustments, one at the peddle and one at the carb. I have a Holly carb and there is an adjustment at the throttle on the right hand side of the carb.
Third, this is a cable system, therefor it may become sticky due to contaminates between the cable and the housing.
Anouther possible problem is that something is interfering with the cable just after the peddle. You can take off the plastic panel just inboard of the peddle and see if there is any obstructions.
If you choose to lub the the cable use a graphite, dry lubercant. If you use a wet lubercant it will collect dust and the problem will get worse.
Hope this helps

I am going to throw this idea out there for those looking for a good lube for moist areas.
It is Remington Dry Lube. Comes in a spray and you can find it at K-Mart!
Used for guns and is awesome!

The traditiona method for lubing a throttle cable is to disconnect both ends & put the pedal (the lowest) end in a plastic baggie. Then fabricate a funnel out of typing paper & masking tape & tape it securely to the throttle end of your cable. Fill the funnel with some motor oil. Set it upright and wait for oil (and likely, water, dirt and rust) to make it into the baggie in front, thus proving that the whole cable is oiled. Let it drain from bolt ends until you get no more slop out, re-hook it up and you should be good-to-go. Worked on my Pantera and countless motorcycles over the years.
One other way of taking slack out of the throttle cable, that I just did yesterday, is to rotate the bracket mounted on the head (I think) that holds the throttle cable. I noticed I had a little too much slack and wasn't getting the secondaries completely open. Loosen this bolt, rotate ever so slightly toward the firewall, just enough to take the slack out of the cable, then tighten. Seemed easier than trying to rotate the throttle cable and adjust the stop nut, as detailed in the above posts...
Another option, anyway...

Hi Wink!! Yes! sold the car, look on the "Blue Book" forum. My email is: thejacks@cnmnetwork.com
The vendors also sell an extension bracket for the carb throttle and a second one for the throttle cable to the intake, to allow full throttle with different carbs & intakes. Dunno what the p/ns are but I saw a pair at PPC-Reno a few weeks ago, all nicely black powder-coated.
