the first problem i had was trying to adjust the idle with the idle knob. instead of increasing the rpms in started sputtering and died. i took the carbs out and cleaned the pilot jets. being an ameture at this kinda stuff thats all i cleaned. after puttin it back together she ran fine and idled correctly for a day. i tried again to adjust the idle and im back at square one. she barely idles and dies with slight throttle roll. im hoping i just need a complete carb clean. but why would the idle adjust do this?
