Quicky question

Spark plugs? They do fail, but not often. What does happen to all plugs is that the electrode gap widens with use, its eroded by its own sparks. A wide gap can cause a weaker spark and possible hot start issues. Plugs are cheap and a new one every now and then is a good move. I would never charge someone for a service and not fit a plug.

 

Needle bearing? These defo need grease, and as often as possible. Weekly is a good idea. Lack of grease does not just ruin the bearing, it wears the drum and the crank. A worn bearing results in a wobbly drum and on some saws, such as the 260 and 360, a wobbly drum can ruin the oil pump drive and even wear the pump casing. A costly repair could be saved by some very cheap grease.
