You need to go to an auto parts store and look at a real spark plug. You'll see the top is different in that there is a cap, about 3/16" in diameter on the top. The automotive plug boot I mentioned has a matching female connection that snaps onto a standard spark plug. Those kit plugs and plug boots are a joke. Get rid of them or you'll continue to have nothing but problems with them.

The kit plug has a threaded portion that is supposed to snap into the kit boot. It is a bad electrical connection prone to failure and poor engine performance. Do not order plugs or plug boots from engine kit suppliers or you'll get the same parts and be back to square one. Replace both with good automotive quality parts and you can forget about spark plug problems.
