Help needed with 318 (timing, ruff starts)

choke is electronic it is set and does work......i have not checked the chain yet have not wanted to open that can of worms yet... as far as rough start it cranks over like it has no fuel or spark but i know it has to or should be getting both i know im getting 6.5 psi of gas at the carb . seems like it just cranks and doesnt hit like it should hell my slant 6 in the duster 2 pedal pumps bam starts every time, then i get in the scamp and have to fight it to start . just frustrating with all the new parts ive thrown at it. but yes i will get a vacuum gauge. what are the settings for that on the carb?
