What is the correct spark plug gap for my STIHL trimmer, chainsaw, or blower? The correct gap setting is 0.020″.
Insufficient torque and debris between the spark plug and seat are causes of spark plugs coming loose. Sometimes the threads in the cylinder head are damaged as a result.
Why Is The Spark Plug Gap Important? The spark plug gap influences the heat range of the spark produced to ignite the air fuel mixture in the combustion chamber. This makes it critical to engine performance.
Spark plug gaps for car engines are typically 0.6 to 1.8 mm (0.024 to 0.071 in). Modern engines (using solid-state ignition systems and electronic fuel injection) typically use larger gaps than older engines that use breaker point distributors and carburetors.
A spark plug blow out occurs when the spark plug is fastened too tightly or not tight enough to the engine plug. The result is that the spark plug itself cannot properly channel the electric charge from the plug to the engine block, and the spark plug breaks down.
Spark plugs are a key part of maintaining a petrol power tool, especially STIHL chainsaws, and you may think that one spark plug is much the same as another. A standard NGK spark plug and NGK spark plugs sold by STIHL may have the same part number stamped on them, but the STIHL NGK spark plug has some key differences.
Faulty spark plugs result in an engine misfire due to incomplete burning fuel. An interrupted combustion process can significantly affect the engine performance. Unattended engine misfire may result in intermittent strange engine sounds, power loss, and engine knock.
Spark plugs that haven`t been changed for a long time can become one with the cylinder head. Fortunately, it`s possible to repair damaged threads instead of scrapping the head.
They are inserted into the hole, and as the bolt is screwed down, the coil expands, creating a tight, firm seal against the threads. When properly installed, helical inserts create a permanent bond that is stronger than the original bolt fastening.

Saw has new vent wont run after hot unless i loosen cap
ANSWER : The vent is not working properly or was installed incorrectly, so there is no negative air entering the tank to take up the space of the fuel leaving it for the combustion chamber. Perhaps your tank cap has a vent as well that isn’t working.
