Spark plug collar/spacer
« on: March 28, 2021, 05:35:08 AM »
Hi everyone.  I've just started work on a 1986 kx500 engine and straight away I'm confused. The spark plug has a collar/spacer underneath it about 8mm tall. It doesn't look factory but without it the plug protrudes all that 8mm out the head into the combustion chamber. Is this normal ?
