How tight should a lawn mower spark plug be?
People also ask, what is the torque for spark plugs?
SPARK PLUG Installation
|Thread Size||Recommended Torque||Recommended Tightening Angle|
|M14||20-30N・m||About 2/3 turn|
|M18||30-40N・m||About 1/4 turn|
|M14 Taper seat||10-20N・m||About 1/16 turn|
Accordingly, what happens if you under torque a spark plug?
In most cases of under-torque, the vibrations inside the spark plug cause the ground electrode to break down, causing serious damage to the part. This restricts the ability to transfer heat to the shell and cylinder head, causing the insulator nose to overheat and starting pre-ignition.
