Hi everyone, this is my first time using this forum so please give me a little leeway. I am new to shifter karts as I recently picked up a kart from my local pawn shop for a good deal. I’m pretty sure the engine on it is from a CR 80. Anyway, I got it running on a jack with the strap on the tire method, put it in neutral, and took it off the jack. I pulled the clutch in and put it into first and the kart stalled as soon as it went into gear. The kart runs fine while on the jack but as soon as I try to drive it stalls. The wheels do spin while the kart is in the air it seems to stall once load is put on the tires. I think its the clutch but I don’t know as I am just a newbie. Plz help
