Hey guys so I've had my go kart finished for a couple of weeks now and it's awesome. The only problem that I'm starting to have is that when I start it the clutch engages and it wants to take off. I have to hit the throttle and it stops but if it sits for a few seconds the clutch engages from the vibration. Is it the clutch? I know I had the chain come off twice and so the clutch takes a beating from it. The outside casing see picture below wiggles. Is that normal?
