    Crosbyman,

    Right on point…I cut off boot and checked new cut wire to coil and got 6K ohms on each coil.  I can’t check for spark right now as I have everything disassembled to access carb for new kit.  The engineering on this McCulloch motor is unconventional but uncomplicated yet quirky.  I had already cleaned the points and the condensors seem to function buy my analog meter is not working so I get dc volts on my digital meter.  You have to remove the power head to remove the carb…not ideal as the carb needs more maintenance.

    Thanks to all who answered…nice to not be walking this path alone!
