Reply To: JAP 2a flywheel removal

Grahame , it would concern me when you said the pulley came of by hand , I can’t help but think all’s not right somewhere and would lead to flywheel/key/ crankshaft failure.All the 2As I’ve worked on the pulley tightens right up , and requires the impact gun to undo.
The points gap is usually stamped into the points inspection cover , I would hazard a guess that your engine has been “got at” at some point in its life.
I will admit to having little to no experience of the external transfer coil system , I only have one machine in my collection that uses it , a Honda F80(the twin cylinder upsidedown engine) , which starts and runs lovely , so thus far have let well done be alone.
Be sure to re-align the key with the cam , looks like yours has moved.
