I haven’t built one yet but I bet you could make a fixture from an old flywheel , i think i have at least a few flywheels from dead powerheads laying around.
Open up the top of the flywheel to gain access to the points by cuttting, grinding, or a hole saw.
you will need to find TDC with a piston stop by the usual means.
Insert a spark plug into the top of the cylinder and Carefully rotate the flywheel till it stops, mark the flywheel at a reference point of your choosing then rotate the flywheel the opposite direction Carfully tll it stops then mark the flywheel at the previous reference point.
TDC is between those two marks.
Repeat for addional cylinders.
Thanks for posting I want to order franks coil positioning tool.
