Why Does the Chainsaw Stall When Accelerating?

[VanJessica]

Here are the possible reasons why a chainsaw stalls when accelerating: 1. Inspection points. Check if the choke is open, inspect whether the air filter is clean, and observe if there's excessive oil on the spark plug after stalling. If oil can be flicked off, it indicates a carburetor issue; if the chainsaw can start at low speed but stalls upon acceleration, it's likely a compression problem, possibly due to gaps between the piston and cylinder or leaking gaskets on the cylinder. 2. Precautions for chainsaw use. Before operation, let the chainsaw run at low speed for a few minutes to ensure the chain lubrication oil reaches the oil line. The air filter should be cleaned every 25 hours of use, and adjustments can be made as needed under special circumstances.
