318 2bbl won't idle without choke

Try this, put a vacuum guage on it.....pinch the fuel hose with some vice grips to lower the fuel pressure. 6psi sounds high for a Carter. Did the kit come with more than one size 'power piston' seals? I had a dirty Nikki carb..had to set curb idle to 1200 for it to idle then I sprayed a half a can of carb cleaner in and around the throat to clean it, it finally coughed and then cleared up big time and wound up to 2000 so I lowered it back down to 750 and it idled great. I think it was some air bleeds gummed up with **** ethanol blend jello as I concentrated the spray on the little brass orifices around the throat. Im now starting it once a week to keep it clear.
