Tillotson 212 is a far better value than Predator if you intend to exceed governed RPM. Predator motors need upgrades to rod and flywheel to safely spin fast (over $100 more right there) while Tillotson is good to go.
I picked up a rough frame with the same model number on it’s tag. Apparently Sears sold karts that we all know but under different model numbers and names.
