removing the breech plug
Carefully as not to cross thread the CO plug
Depending on the maker you can remove the breech plug and of course the sights and underlug. It is not an easy task to remove the plug and without proper tools usually results in a buggered up barrel or plug. You would need a barrel vise and a breech plug wrench, some heat and penetrating oil. I would recommend taking it to a gunsmith in your area.

The plug gapSpark plug gap should certainly be between 0.6 - 0.8 mm. When it comes to spark plug itself, we highly recommend NGK spark plugs, either B9ES with a more lengthy thread) or B7HS (shorter thread) for general use. BR9EIX (a bit longer thread) or B7HS-10 (shorter thread) for competition driving. For more advice search 'pocket bike manual' in google.

damaged thread in head or spark plug. not tightened right or damaged plug
if sparkplug came out, then you need to find the problem that causes this. usually plug will blow out if it has been loose and trashed the thread where it bolts in. easiest way to fix this is to buy a spark plug with a speeedy sleeve. as you screw this plug into the plug hole a sleeve in the plug will make a new thread replacing the old one,and allow plug to be reomved for service in the future.
