When I go to start my CJ in the morning or when it hasn't run for a few hours it takes forever to start. I have to crank and crank and crank it over until it catches. When it's warm, no problems... I'm about to switch out the carb to a weber but I wanted to understand why before I switch it...
With the engine stone cold pull the air cleaner top off. Have someone step halfway down on gas pedal and release it while you're looking straight down the throat of the carb. You should see the choke plate open slightly and then drop closed. If it doesn't close, there's your problem.
Next, hold the choke plate open with a screwdriver or something (that won't fall in). Shine a flashlight down the throat and have someone push the pedal down. You should see a squirt of gas. If not, there's your problem.
BTW, most 2bbl and 4bbl carbs on the top of V-8's will take in excess of 10 pumps to flood. My little 4 cylinder takes 4 or 5 pumps to start cold. And mine's on a manual choke.
