Last night i took off the carb for a cleaning.. my first time. So i seen a couple of guides that show how to take it apart and put it back together but neither talk about what to do with the 3 adjustment screws.
I understand how to adjust the air and throttle but what do you do with the bottom screw thats near end of the float cap? Put it in tight? Whats that one for?
