Hi - Im new here. I just rebuild my carbs, the needle value adjustments at top of carb where between 5 - 6 turns out and I set them back the same way. The motor starts and runs great throughout rpm range took it on a 20minute run, but idle is alittle over 1000rpm. If I adjust the idle down to 875-900 I cannot get engine to stay running. I tried adjusting the needle value adjustments at top of carb but they seem to have make no difference after 3 1/4 turns out. What is poper way to adjust these valves. Thx in advance.
