SPARK PLUG

To remove a sparking plug use the box spanner and short tommy bar provided in the toolkit. If the plug is difficult to unscrew, poor some penetrating oil round the threads and allow it to soak before continuing

I change my sparking plug every 2,000 miles, I remove the sparking plug and  tested on the plug cleaning machine. If there is no plug  cleaning machine available use a penknife or wire brush to remove carbon deposit. Measure the gap with feeler gauge ; The correct setting is 0.025 in(0.653 mm) . To adjust the gap bend the side electrode but never the centre electrode. Every 10,000 miles fit new spark plug
