What is the correct spark plug gap for my STIHL trimmer, chainsaw, or blower? The correct gap setting is 0.020″.
Replacement Plug
The Craftsman 4.5hp mower uses either a Champion model RJ19LM or J19LM spark plug, or equivalent, with the gap set at . 030 inch.
These plugs are pre-gapped at . 044″.
Clean the spark plug. Check that the electrode gap is 0.020 inch (0.5 mm). The bar should be turned daily for more even wear.
The distance between the tip of the spark plug and the central electrode is called the “spark plug gap” and is a key factor in the function of a spark plug. Spark plug gaps for car engines are typically 0.6 to 1.8 mm (0.024 to 0.071 in).
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.
Signs of a Bad Spark Plug
If it has fuel which isn`t blocked from entering the piston anywhere (like the carburetor, if the fuel has been sitting unused in the tank for too long), it should start. If the gas tank is full and the fuel is good but your small engine won`t start, you probably have a faulty spark plug.
A) For 28-32 cc engines, set the gap at 0.020″ (0.5 mm). B) For 38-55 cc engines, set the gap at 0.025″ (0.635 mm).
SPARK PLUG GAP: 0.51mm (0.020 in.)
