I need to check the timing on a 1966 Vespa VSCIT. I have downloaded a deg. disc but not sure how to use it. The timing should be 26 deg. BTDC. Any help is appreciated.

do you have a piston stop or is the head off so you can determine TDC?

I don't have a piston stop and the head is still on but I have found a procedure on ignition timing under Team Vespa. I may use a screwdriver to determine TDC and an ohm meter to determine the current timing using the deg. wheel. Previously, I had removed the stator and had to rewire it due to the original insulation on the wiring had crumbled off. Before removing the stator, I marked its position but, must be off due to noticeable power loss going up hills and poor starting when engine is warm. All help is appreciated.

Old topic but in case anyone comes across this here is a video about timing an older Vespa w points:
