Hey guys, I got some yard karts for my boys. The parts that came with the karts are unfamiliar to what I'm used to seeing, including the sprokets and heavier duty #40 chain. I see a few torque converter components. Please tell me about parts you attached and all/any suggested use. Also on two of the karts, the sprockets are 49 teeth on them in which I have already ordered a 10T clutch for it and the third one has 66 teeth in which I have ordered a 12T clutch for it. As you see, they all have 6inch tires. The engine I got for one of them needs to be lifted higher so the bolt from the clutch will not touch the tire. I would deeply appreciate any help, advice or suggestions.
