wont rev

Sounds like your bowl float is not properly set and you are draining the fuel bowl. Another possibility is your fuel pump is weak and not pumping as it should.
Also wonder what your initial timing is on your ignition. You should be running 10-12 degrees,and about 30-34 total advance, with the stock distributor.
Have you checked inside the distributor to make sure your centrifical advance is working? One rudementary tes, take off the distributor cap and see if you can move your rotor by hand. You should be able to move it clockwise by about 10-15 degrees, and when you let go it should return to the origional location, by the spring tension on your centrifical advance.
For some tips on playing with your stock distributor, give me a pm.

according to my books......base timing should be 6 degrees stock.......im running around 10 right now......i dont think the float bowl is running dry........but it might be the fuel pump.....only reason i say this is because when i first start up the car in the morning or whatever........it starts right up runs nice but within seconds it starts to run real crappy so thats my take on it....unfortunately i cannot achieve WOT right now because the stock linkage is too short...but how would that not let the car rev and stay running?....when i rev it......it seems to be struggling to gain rpm then when i let off it putters and dies....i have yet to check the distributor for that play but last time i was in there i believe i experimented with that and i remember there being spring tension on the rotor....the fuel filter is less than 2 months old and is visible for me to check regularly but i checked and its got a little crud in there...thanks for your help

no revs

10 degrees is about where you want it. Didnt think about the fuel being cruddy. Take the origional throttle linkage bracket loose, and see where it should be at WOT. Then find a way to mount it there.
