Need help fixing buddy's Stihl 009, has no Spark as tested with spark plug installed and using known-good spark tester. Two questions: 1) does Kickback/ChainBrake have any connection to Ignition system? This spring-loaded ChainBrake seems odd as it is always in the Forward (i.e. kicked back) position. 2) the Sliding Kill Switch when moved forward contacts a metal plate which is always contacting the Flywheel therefore connecting to Engine Ground. See photo with multimeter probe pointing to the plate. This seems to be a fault--i would think the Kill Slide would need to physically move the plate to contact the Flywheel thereby grounding any spark. Thanks for any help.
