Well, I inspected all hoses. They seemed good. Then I made sure all the bolts were torqued to spec. Then I sprayed carb cleaner by the intake gasket, carb to intake, and anywhere else where I thought a leak could be. No change in idle. I know its not full proof, but what else could I do? Just as info, when I hooked up the gauge, Im running at about 14.7. Also, when I cover up the secondary air bleeds, there is no change in idle. I am idling at about 1000 rpm and when I drop it in gear it goes to about 850. Does this all sound good to you guys?

When you move throttle there is a nice(immediate) steady stream of gas? float level is correct(at bottom of sight plug) What jets are in there? Are your end carbs are vacuum activated? Suggestions (1) disconnect/plug the vac hoses to the end carbs to isolate them from the center carb so we can concentrate on fixing the one center primary carb & (2) richen up the center carb jets 4-6 sizes & see what happens. Holler back when you can. PS I am not sure if plugging the vac lines is needed or will help us but I do want to isolate the center carb to narrow down where the problem is & for sure richen up the center carb for a tryout. Almost forgot what do your plugs look like?

This sounds okay. You should cover up the center carb idle air bleeds to see what the effect is on the idle quality. It should not stay the same.
If the squirters are working properly and the idle mixture screws don't fix the hesitation, I would take the center carb off and go through it focusing on the idle and transition circuit.
