Kart problems.

[Jeff15]

Hey yall. Bought kids a go kart and it will not pull. We replaced clutch did oil change etc. Still no go. With or without someone inside still will not go. It will crank with no problem and if the rear is lifted the rear tires are going at full speed. Once kart is on ground and is trying to accelerate its a no go.
Motor is honda gx 160.
Anyone can help?

Hello and welcome...
post some pics of the kart...
Also what is the gear ratio(tooth counts of both sprockets), OD of the measured tire size of the rear....

 

[Jeff15]

Clutch has 10
OD tires 14in
Axle 60 teeth

That motor is relatively under-powered for this machine...
with that being said... might need to increase the rear sprocket size... but that might be easier said than done....
Are you oiling the clutch every 2 hrs of use???
Is the foot throttle moving smoothly to the throttle plate??
