Brave 72 318-3 spark plug makes clicking noise

[Willyboy]

The 2 left front (while looking in front window!) sparkplug seem to do a clacking or clicking  sound and do jerk (jump) a bit ?? Any ideas on whats happening here ? Thanks for any clues!

Two years ago, I thought I was about to blow an engine when an INCREDIBLY loud rattling knock suddenly happened. The ceramic had broken free in the metal housing and was rattling in the metal plug body with each stroke of the piston. Amazing it didn't get sucked into the combustion chamber or blow out completely into the engine compartment!!! But that bouncing rattle sure was LOUD!!


In my experience, spark plug failure is rather uncommon, but I've notice a recent decline in quality in some brands!!! Disappointing to say the least!!!
