clutch help

[STC]

i have a BS fun power 5hp kart i just picked up in parts
when i checked it out i tested the motor on the floor and it ran fine. I reassembled the kart got it running. problem is when i start it on a bucket with the rear wheels off the ground it runs and idles fine. soon as i put the wheel on the ground it dies is there anything i can do to adjust the clutch ? im sure this is the problem

do you have pics? i think your gear ratio is the main problem but your clutch may be engaging too soon. can you give me your gear ratio and tire size? also is your kart a big 2 seat kart or a 1 seat fun/yard kart

See if lowering your Idle speed helps.

It just sounds like the clutch is worn out, try at first oiling the clutch where the snap ring melds the inner and outer half, if that does not solve your problem the spring and or bushing is worn out, it may be time to buy a new clutch. Congratulations on getting the engine running.
