    I heard a beautiful sound tonight.  I don’t know about size, but AWG does matter.  I pulled out a heftier set of jumper cables and she turned over quickly, smoothly and quietly.  The wire harness also had no problems cranking.  My compression topped out at 100 in both cylinders.

    I will put the lower unit back on this weekend put her in barrel of water and see how well I did at cleaning and rebuilding the carb and rebuilding the water pump.

    I am still not sure what year the power head is exactly.  It is definitely not a ’61 but I can’t find any other numbers on the power head.
