Hey Mike,
I know that it has been nearly an eon, but I do have both a door handle and fuel cap that could probably now be successfully scanned and 3 D printed.
Marvels of modern technology!
However in an otherwise (grind) stone age vehicle I am currently befuddled by what appears to be a crude version of a magnetic pickup type ignition system mounted about the crankshaft's end that looks like it must somehow be triggered by the rotation of a couple o f square shouldered (woodruff?) keys located in keyways cut into a collar quite steadfastly mounted on the end of the crankshaft.
One for forward, and one for reverse timing?
Should they be magnetized? Mine currently are not demonstrating this property.
Yesterday I made a puller plate and exerted quite a bit of force on the key retaining collar at the end of the crank to hopefully allow me to remove the pick up assembly for bench testing. But despite a strong pull, it refused to come off.
Other than the seemingly unlikely existence of a set screw or roll pin of some sort hiding under the key ways, or it being a very strong press fit, I have no clue as to what is retaining it, and still do not really knowhow to test or fix the system.
Suggestions welcome!!
