Got a bike engine that just won't fire up? When your magneto and CDI have a current but electricity's just not getting to your motor, it's time to replace your spark plug with this 2-Stroke Motorized Bicycle Spark Plug. With a spark plug gap of .6mm (~.025"), this spark plug is designed specifically for 48cc and 66cc 80cc bicycle engines.
Without a spark, the fuel in your engine won't ignite to create the explosion (i.e. combustion) needed to move a piston and crank in order for your motor to run. When you see your spark plug blacken and corrode, just use a spark plug tool to simply unscrew and remove the plug, then simply install this new spark plug in its place. Once you do, you'll be able to pedal or pull start your motor and get it running the first time, every time.

When we received the correct ones, they worked great.
Stuff was as described and showed up early.
Quality Spark Plug The spark plug that originally came didn’t work, but this made a great replacement.
General comment For thoses who are not aware of this. You will go thru spark plugs faster, in a two cycle engine, then a four cycle. It has to due with the mixture of oil & gas in a typical two cycle.
