RE: OS 50SX tuning/glowplug problems..
I was running a Magnum 61 four stroke and I got close to it from the rear to use my Glow Bee tach on it when the plug blew out right past my head.
I had used one of those Dubro Tee wrenches to tighten the plug and it must have bound up against the head?
That was $10 worth of experience for a OS"F"?
Enjoy,
Jim
