HI all,

Just wondering if anyone has experienced failure of the YS ignition plug after only 10 flights.
My 175z cdi refused to rev at high throttle .....misfiring and not making power throttle back and run good below 3/4 throtle

Removed the ignition plug and noticed the top part detached from the main body.........this is the second time first plug 20 flights and second 10 flights

The plugs were both new and genuine YS parts.

Just wondering if a bad batch worked themselves into circulation or something else is causing these failures


regards
