Do Pakistani mechanics properly gap and install spark plugs in Changan Kalam during routine maintenance?

Improper gapping o r careless installation can lead to misfires and engine knocking. Is this happening due to lack of expertise in local workshops?

Often no:

Many mechanics don’t use a gap gauge.

Incorrect torque o r cross-threading can crack the plug o r strip the cylinder head.

Misgapped plugs cause weak sparks, engine knocking, and misfires.

➡️ Insist on digital gapping, and always verify the plug model number.
