Row Boat Motor Magnetos

Thanks for the replies regarding batteries.
Regarding "setting" the timer for starting
the motor, do I want it at TDC, or slightly
retarded so it doesn’t kick-back and break my
hand? 😮
Thanks!

I would start after TDC,maybe 20 degrees, and work backwards. My RBM fires at TDC when the timer handle is straight forward.

Thanks Tom. It worked out that on my "center" detent, when
the timer handle is horizontal, the motor will fire slightly
after TDC.

Tom,

You are one crafty guy! I love this thread.

I shortened the magnet to make it look better, and not
stick up as high for cranking the flywheel, using a chop
saw, bench grinder, and belt sander. Guess that was
the easy part. Tried to drill a couple of holes in the
side of the magnet for mounting it to the timer,
but my drill bits wont touch it.
What kind of super duper metal was that 1930’s
magnet made of, and what kind of drill bit do I need?
Thanks.

Update- have not researched for a "magic" drill bit for
the above problem, but did bench test the timer out
this afternoon. Looks like it’s a "go" so far.
