Since nobody replied I will give it a shot...When you retarded the initial timing did you add more centrifugal (sp?) advance? Because if you didn't then your total timing is probably to low. Also, even if you have a mild performance cam it will probably run better with more initial advance than 8 degress, I would bump it to 14 or 16 and see how it reacts (plug the dist. vacuum canister when setting your timing). Remember to check your plugs for signs of detonation. Once you have the timing fixed I would move onto the carb, you should definitly see gas coming out of both sides of the squirter which by the way is not a jet, your jets are screwed into the metering block, you would have to remove the bowls to see them. I hope that last sentence didn't come out wrong, I'm assuming your looking at the accel. pump squirter and if it's clogged you can remove it and soak it in some carb cleaner.
Another thought, if you hooked up your distributor vacuum advance to direct manifold source (below the throttle blades) that could have signifigantly raised your initial timing. Keep us posted on your progress.
