I just got my S30, I broke it in last night, and went bashing with it today. While i was cruisin around, i wasnt paying attention to how much gas i DIDNT have and it ran dry. I went and filled it backup, tried starting it, and nothing happend. i thought maybe i had flooded it, so i went through the steps to clear that out. While pulling on it, i noticed the pull cord was lagging while retracting and wouldnt go in all the way, i had to rotate the fly-wheel to get it all the way in. I took the pull start off to see what was goin on, nothing was wrong. I put it all back together and tried to start it....nothin. so i took the glow plug out anff put a few drops of nitro directly in, and that finally worked, but then i noticed all the tuning was messed up. Any ideas why it would do that?

sometimes the clutch spring will wear in a little and start grabbing, sometimes they break, could be the issue, also can be an air leak. if it held the new tune and ran fine then your good.
