I bought a referb BME 110 from Tom, got it all mounted up in my 75cc Aeroworks Extra 260 for some 3D. Well she would not start. No spark ! I found it to be the Hall Sensor pick up. I could hold the wire at just the right spot and had spark. It is Saturday so I left Tom a message but wanted to get this ready for Sunday !! So,, I cut it apart and found the red and white wires broken at the solder joint. No problem to fix, but a little miffed I got a worn and vibrated sensor that some one did not strain relief.
