Wanted to open this as I bought the fox 70.

TOPIC 1) clutch not set correctly as purchased: it will not even move the tires when stopped on the slightest GRASS hill with my 62lb daughter riding.
NOTE IT IS PERFECT ON FLAT GROUND.

Please don't point me to the throttle adjust screw as that is obvious and already removed.

FIX searching: I am an engineer trying to learn how to fix this issue.
Question: seems the clutch is not engaging enough thus it just BOGGS OUT ?? So the adjustment screw would need to be backed off, ie turned counterclockwise?

2) sprockets: I don't need it to set land speed records for my daughter. I forget the front sprocket size but the rear is 37 tooth. I may go up to a 43 or larger for more torque.
Question: can somebody reply WHERE to BUY replacement sprockets that fit the fox 70?

I will post whatever I can find along with any success and failures to resolve these.

Please add any fox70 topics to this thread for the rest of us owners to share/discuss.
