Couldn’t leave it alone.
Checked another motor with its timer centered over the
mixture screw to find the flywheel position when it fired.
Positioned this timer same as the other motor and rotated
the flywheel till the points opened. Exactly the same spot!!!
Although you wont be able to start it by turning the flywheel
backwards as you normally would a Super Elto, by spinning it
forward or using the (missing) rope sheave it should start
and run. Amazing (to me anyway).
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
