Re: cleaning and resetting points

(Point Setting Of Magneto Models)
(J. Reeves)

Set the points as follows. Have the flywheel key aligned with the fiber rubber portion of the ignition points. Adjust the gap so that a .020 gauge will pass thru but a .022 will not. Should there be any question of the points being dirty (touching the contact with your finger would cause them to be dirty), clean them with a small brush and acetone or lacquer thinner.
NOTE: Should the operating cam have a small portion on it with the word "SET" imprinted, align this portion with the fiber rubbing portion instead of the flywheel key.

(Regular Magneto Coils - Continuity Test)
(J. Reeves)

Checking the continuity of the ignition coils....... Have the ohm meter set to High Ohms.
Remove the primary wire from points. Remove the coil ground wire. You do not want either of these wires touching anything.

Connect the black lead of a ohm meter to the spark plug boot terminal, then with the red ohm meter lead, touch the ground wire of the coil.
Then touch (still with the red lead) the primary wire. You should get a reading on both touches (contacts). If not, check the spring terminal inside the rubber boots of the spark plug wire.

If there is no continuity between the secondary circuit (spark plug) wire and the primary or ground, remove the coil from the armature plate, then check the continuity directly between the prong within the coil (prong that the plug wire connects to) and the primary and ground. Poor or no continuity of a coil (or plug wire) is one reason for weak spark, s/plug fouling, or no spark.

Re: cleaning and resetting points

what postion should the throttle been in? It has two setting on the flywheel how do you line these up? On the top of the shaft it has top imprinted on it.

Re: cleaning and resetting points

The throttle may be anywhere.
If you have the 'special tool', lock it in one way or the other so the armature plate does not move. To get the ignition optimal, it is important that the crank is turned exactly 180 degrees between the point openings. With the tool that happens when the 'arrow' of the tool is between the marks on the armature plate.
If you do not have the tool, use a caliper, dial-gauge or piston stop to be sure you adjust at 180 degrees difference.
