First of all what is a spark plug? Spark plug is a device used in an internal combustion engine - that is, an engine that derives its power via exploding gases inside a combustion chamber -to ignite the air-fuel mixture. Time to time carbon builds up on the tip of the spark plug that delivers low mileage and can damage the whole engine. As factory advice it is a must to replace your spark plugs ever 100,000 miles.
It’s a must to check your spark plugs every 5000kms to your for any carbon build ups that can cause fluctuating rpm and poor combustions. Here are some steps on how to clean you spark plug.
Step1 Disconnect the spark cap or high tension wires
Step2 Remove spark plug( you will need a spark plug wrench) take fine grit sand paper or steel brush then brush the large threaded end of spark plug till you see silver metallic color.
Step3 Dip large threaded end of spark plug in bottle cap of gas/kerosene, then lay on nonflammable surface and light allow to burn out and cool this will get rid of all carbon build up on spark plug.
Step4 Check the gap of the tip of the plug using a feeler gauge, be sure to follow the correct gap specified by the manual. If you don’t have a gap gauge for the spark plug you can gap it with the skinny end of a butter knife be sure to use and old one for this can damage the knife.
Step5 Reinstall the spark plug to the motor. Be sure not to over tighten the plug to avoid loose threads.
Step6 Reconnect the spark plug cap or high tension wire. Start the motor then your good to go.
