[Kartbuilding] go kart advice

[Stephen Burke]

Hi,

If the centrifugal clutches burned out very quickly, then yes - the 
gearing is incorrect.
Did the second-hand kart look like the one on this page:

If so, then typically these karts are designed to run on the flat, and 
they have a slow take-off with high top end speed.

Typically centrifugal clutches on karts have 10 teeth, and 60-70 on the 
rear axle. Typical centrifugal clutch and sprocket:

Your best bet would be to either get a larger sprocket for the rear axle 
or a smaller one for the engine/clutch.

Best of Luck,
-steve
