I'm still having trouble getting my monojet to Idle on my 1970 C50 with 292. I have been through everything carb has been cleaned out twice. all new tune up parts set points/timing checked several times for vacume leaks etc. It runs better off Idle but rough at Idle. Idle mixture screw must be almost all the way out for it to run. This is a carb that was apart before I got it. looks like it is together properly now. It was leaking down originally, that has stopped. is there anything comon on these monojet carbs that gives them a rough Idle? I've had several monojets in cars over the years and never ran into this? It runs better with choke slightly closed, but not much better. Definitely appears to be running lean. I've been looking for another carb to rebuild but no one has any left around here.
