The term "seize" is always used in jargon. In practical terms, this means that the piston gets stuck in the cylinder and that, consequently, the engine stops. In relation to motoring, it is one of the most common setbacks for karts, and when it happens ... it is never a good thing. This is because the seizure blocks the wheels and can lead to risks on the track, and the engine can be seriously damaged. There is no fixed rule to make sure you have no seizure problems. The advice that we can give, in general, is to always keep several parameters under control that undoubtedly have a decisive role in the occurrence of this problem: mainly carburation and temperature.
