That changes things a bit. No worries :thumbsup:
The gap is still .020.
1. Take off the cover and disconnect the spark plug. Rote the engine until the points open their widest.
2. Check the gap. To adjust, loosen the top screw and move the base of the points with a screwdriver blade until the gap is correct.
3. Tighten all the screws and replace the cover.
To verify timing:
You'll find a "timing sight" hole in the blower housing or the bearing plate. It might have a cover - remove it.
Turn the engine over - the way it usually rotates, you should see either an S or SP mark (with compression release) or a T (without). The points should just begin to open then. If it opens early, narrow the gap a little, to .018. If it opens late, widen the gap to .022.
