hi, 351 ford PMC, Carburetor and points. First it takes a long time to warm up more than 5 min. this year its runs very rough at idle
and stalls even after it's warmed up. Idle speed it a little low, 600. Runs fine above 1200 RPM. Plugs look ok , I ordered a new coil as I noticed a hair line crack in the neck but have seen any arcing I haven't done much to it in 5 seasons it only has 500 hours on it. Played with the idle mixture screws but it didn't help. Thinking about spraying some carb cleaner and maybe just increasing the idle. Is there any way to check or adjust the choke? Any suggestions?
