Car wont idle, any ideas?

Make sure none of the carb linkage is interfering with the manifold.

I usually disconnect and plug everything from the carb to identify the culprit. If it still acts up it's the carb/gasket, etc. Hook stuff back up one at a time to see if the idle changes. I wonder if the plunger springs are too stiff for that cam/vacuum and they are allowing the needles to ride up.
