To know if your 2-stroke engine is blown up, look for signs like excessive smoke, loss of power, and unusual noises during operation. A thorough check might reveal scored or damaged piston and cylinder walls. Also, if the engine fails to start or has significant oil leaks, these are strong indicators. Conducting a compression test can further confirm internal engine damage. Immediate inspection and repair are recommended to avoid more substantial damage.
