If your chainsaw runs for 30 seconds then dies, it likely points to issues with fuel supply, air intake, or spark plug. First, check the fuel mixture; incorrect ratios can cause the engine to stall. Next, inspect the air filter; a clogged filter restricts air flow, leading to shutdowns. Lastly, examine the spark plug; a dirty or damaged plug may prevent proper ignition. Addressing these areas can often resolve the problem, ensuring your chainsaw runs smoothly again.
