By dead spot i meant that when i step on it it kinda hesitates(moment of silence) then will go...to check the accelerator pump do i just push that pin out holding the arm in place and c if it will rev better? Or is there a different way?
The hesitation means it's either getting too much fuel at that moment and can't burn it (in which case the exhaust should be black/rich), or not enough fuel and the mixture is too lean to burn right - since your plugs are white, methinks it's more likely to be a lean condition.
Motor off, air cleaner off, look down the primaries. When you push the linkage to open the primaries (simulating that you're stepping on the gas pedal), it should push the accelerator pump lever up at the linkage, meaning it'll push the little pin on the left front top of the carb (i.e. the acc. pump) down into the carb. When you look down the primaries while you actuate the linkage, you should see/hear/smell a spray of fuel.
If it doesn't do that, my guess would be that the little gasket skirt on the accelerator pump might be broken/kaputt and needs to be replaced as it doesn't seal anymore. For that, the top of the carb needs to come off, and you'll need a carb rebuild kit (which usually contains a replacement accelerator pump).
If it does spray fuel, could be it's not enough. One option might be to look where the pin from the linkage connects to the lever that pushes down on the acc. pump. There's typically two holes where the pin from the linkage (not the pin that serves as fulcrum!) connects; those two mounting locations mean you can get a different amount of stroke onto the acc. pump via different travel/engagement of the lever.
If that's maxed out, you're gonna have to get the Doug Roe book on Q-Jets (as I said I don't know 70's Q-Jets that well).
Yet a different possibility is that the timing is not right and you'd need a little more advance to allow the mixture the time to burn.
