Howdy Gena,
Q: What would you advise in this "chain drive issue" scenario?
"Here's what problem I keep running into with a drifter kart:
I have a 224cc Predator engine, live axle, 30 series torque converter (1 new out of the box), 72T sprocket, 10T jackshaft sprocket and a #35 chain.
I can't keep the chain from coming off. I have tried running with it loose, snug tight and every position between both extremes"
