When I took my driven apart, it wasn't that hard to put back together - but I think I needed a knee, a foot, and both hands.
I've never really messed around with driven spring tuning, so I don't have much experience. Wonder who put it in the 1st hole? They usually come in the middle one which is probably best for most general use.
Test, tune, repeat.
I wouldn't be able to tell how the the Engine/TC responds to a 10 degree hill with a change in the TC driven setting even if you told what size wheels the skateboard had or how many spark plugs where in the 39cc engine.
