318 2bbl won't idle without choke

Throw another carb on it! Im sure there are at least 5 on this board that have gone from a 2 to a 4bbl and are just waiting for a reason to touch that 2bb again. I got 2 2bbl intakes for a LA and I don't even know where I got them! sorry, no 2bbls unless you want a completely worn out Nikki 2bbl from a Mazda. I suggested a vacuum gauge a few posts ago. If its fluttering crazily, you may have a burned valve, that will throw a wrench into any carb tuning your trying..... remove the valve covers, and take the rockers off, check your valve heights. Remove the carb and put a shop vac in the tailpipe. Listen for hissing in the intake. Just runs so rough it looks like a vacuum leak. pinch all vacuum hoses or remove them and plug them. process of elimination.
