Hi

im posting this to let you guys know that i did figure out what the problem whas

heres what i did i started looking at the carburator again
so my first test whas to rev the enginge up to the piont where it starts to die
at that point i did take a spray bottle with gas and sprayed in to the throuth of the carb instead of dying it picked up as long as i feed it with gas

long story short after looking through the carb again not really noticing anything obvious
i did decide to try something i took the smallest drill i could find and drilled the main jets
but the carb back together and now it runs ok it revs up like it should and drives ok

the main jets in the carb had the number 49 on them dose anybody know what size i should have for a 307 chevy or a 350 for that matter
