Flywheel timing marks Bosch 1971

[t20sl]

Has anyone ever run into flywheels with no timing marks on the Bosch points ignitions?

[Doug Wilford]

Replacement Flywheels that were not used in production sometimes were not marked.

Thanks Doug.

Set the timing with a dial indicator and then set up some marks of your own. Then you know it's spot on.[^]

t20sl,
If you have never done this before maybe this will be helpfull
To find TDC you need to make a mark with a felt pen at some measurement before the dial indicator shows TDC. Use some thing Like.020 . Then go through TDC and make another mark at .020 after TDC indicated. Half way inbetween is TDC. The flywheel will rotate  some after you first see the needle stop . Enought to throw off you second mark for firing.
Hope this is some help,
John D.
