Shouldn't need a puller to pull the flywheel off with the Twins.I never have should just wriggle off.Depending on which model motor you have it may not have point as I believe I think it was the 3rd updated engine had electronic ignition.
As for the picture you asked for here is the coil set up.
Not real hard,1 wire runs to the earth.
The other two that come off the same connection,1 runs to the points and the other to the carby kill switch wire.

Here's what the points look like.This engine is the first of the Twin engines and isn't one of the updated versions.So it didn't have the dust cap to cover the points.The updated engines did.That's why you can't see the rubber o-ring on the ignition plate.

Hope they are of some help to you.

Here for a good time,not a long time.
