Why Won't the Stroke Engine Start When Pulling the Cord?

[CassidyFitz]

If a stroke engine won't start when pulling the cord, it could be due to the gasoline engine's connecting rod seizing with the crankshaft (bearing seizure), or because of a carburetor malfunction. In such cases, it is recommended to seek assistance from a professional repair technician. Common faults in gasoline engines include: 1. Detonation: Gasoline engines may experience detonation. To analyze the occurrence of detonation, it's necessary to understand its causes and address the root issues accordingly. 2. Cylinder Scoring: Cylinder scoring refers to the phenomenon where vertical scratch marks appear on the inner surface of the cylinder liner in the area that comes into contact with the piston's reciprocating motion. Generally, cylinder scoring often occurs during the break-in period after an engine overhaul, but it can also happen during normal operation.
