We thought we had our clutch problems on the go-kart figured out, but they rose again. Got the clutch torn all the way down last night, to find that the key was rounded off, with a piece stuck in the sprocket. The sprocket also has 3-4 spider cracks along the keyway, and that the teeth were completely worn out. Will pick up a new key and sprocket this week, then ride out!
At least our predictions were correct about it rounding off the key, so we will fix it and go again. Once it is up and driving again, it will go down for a bit while we put our T25 turbo on it
