Great video,you made checking advance look easy.I'm doing that to every saw I build from now on.

[@patrickwhalen4781]

For a saw like this, how would you advance or retard the timing? Can the coil be moved laterally for that purpose, similar a non electronic system like the stator plate on an 041 that rotates (and therefore rotates the coil)? I’m only familiar with the coil being able to be moved further from the flywheel magnets to increase the air gap.

[@VintageEngineRepairs]

No the stator plate cannot be moved. These ignitions are fixed, however if you wished to advance the timing a few degrees for better top end power then you shave the key slightly and turn the flywheel on the crankshaft stub.

Great video. At 5:35, are you making the mark with your pen while you’re running the drill and timing light? Seem like it could be tricky to be exact.

[@VintageEngineRepairs]

You spin the engine and use the light, put a mark where you think it seems to be landing and then check again. Re mark it if necessary. That’s what I did here. Took two attempts to get it exact. First was a close estimate second was the exact position.

[@williamemerson1799]

Well alrighty then.

[@14maros]

At the start, the ignition angle is also 26 - 28 ??

[@VintageEngineRepairs]

Yep, It’s fixed.
