Tore into the gearbox tonight, didn't find anything out of the ordinary. I just wonder if this a symptom of a bigger issue going on?
When driving, the kart seems to have more vibration than normal.
And upon removal of the gearbox, I found that the chain gets tight, and really loose depending on the tire rotation. I know a tight point is normal for chains, but I'm talking tight, rotate the wheels a bit and I have 1" of slack on the chain, then it gets tight again. 0 - 1" of slack seems very excessive to me.
Here you can see the problem I was talking about. (but never was an issue until after the new rebuild)
And in this pic, you can see how I moved the sprocket to the passenger side to see if the chain was "pulling" it towards the engine. Sprockets are now out of alignment
