Joe, I took a photo of the inside of my flywheel showing the keyway and
the close approximation of the rivets, marked by the copper washers.
Will try to compare mine to Mumbles
It would be nice to see a pic of the flywheel tab in correlation to the flywheel key. Hopefully someone reading this has one so we can rule that out. I’ve looked all over internet can’t find one.
Also after I looked at your some of your pictures I see the throttle advance moves to the right for faster so engine would spin clockwise more than likely. It would have to move to the left for faster if counterclockwise.
Yes, engine runs normal, clockwise direction. Looked at a couple HS-10 Johnson
on Youtube just to make sure!
This morning I re-cleaned the carbon brushes, their springs, and the brass bore
they go into. Also removed the brush tower screws to look underneath.
I could only lift them about 1/8" because of the wires soldered on, but
using a light and mirror I seen no signs of arcing. For the heck of it, I
put a piece of "fish" (insulating) paper under each tower, and behind
each tower along the laminates. Then I coated what I could on the
bakelite towers with Super Corona Dope. Just letting it dry for a while,
then will put it back together, and see if I can test it with the timing light.
Bucc
Joe
ps I am guessing if you got double fire on both cylinders after checking bakelite could be off 120 degrees or points cam is upside down which I don’t think would make a difference since it has 2 lobes but worth checking.
