I wanted to drain the carburetors for winter storage. Unfortunately I unscrewed what turned out to be the the idle jet screw ( looks similar to the carb drain screw ) on the right carb. After multiple turns out I figured it was the wrong one so I screwed it back in. It seated finally and I snugged it down until it felt "spongy" like it could be tightened a bit more but I stopped. I have no Idea if its set right now but the bike seems to Idle and rev up ok. I thought of trying the other side to see how many turns ( if any ) it is turned out but for now hands off until I find out more about it. Does it make sense that the screw would be correctly set turned in all the way?
