I have replaced Coils, condensors, wires, and points. Cleaned magneto and can get spark on 1 cylinder only. After switching everything around numerous times, changed non firing side back to old spark plug wire now that side sparks but the other, which sparked , does not. The point kit came with capsules of grease that i was told to put on point contacts that touch the drive stem.

THere is nothing worse than chasing an electrical problem that runs amuck... make sure the points contacts are clean - making flat contact with each other - have the proper gap at max opening. When greasing the points cam/points rubbing block.. you need only a SMALL amount of grease.. usually putting some on your finger then rubbing your finger and thumb together to reduce the excess grease..then rubbing your finger on the points cam will be all you need. Excess grease will/possibly cause problems.
After you check all the items above and they are correct....? ..I am at a loss to explain the "changing" of the firing.. its obviously something you changed to make it swap.. try changing one thing at a time as see when/if it happens again... write down what you do as you do it.... it helps in the long run!
Good luck! -
(Point Setting Of Magneto Models)
(J. Reeves)
Note that there are other ways to set points such as using a ohm meter or timing light... however, the following will result in a setting so close to being exact that one could not tell the difference.
Make sure that your feeler gauge is absolutely clean so as NOT to transfer oil/grease to the points.
Set the points as follows. Have the flywheel key aligned with the fiber rubbing 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 1: 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.
NOTE 2: Should the cam have the word TOP embossed on the top of it, that is a cam that could be installed upside down and this is simply telling you which side is up. It is not a position where one would set the points.

(Magneto & Driver Coil Alignment)
(J. Reeves)
To align the coils properly, have the metal vertical portion of the coil yokes aligned with the inside edge of the bevel that exists on the top portion of the aluminum seat upon which the coils sit. This creates the proper distance between the coils and the flywheel magnets. Faulty alignment creates friction and the yokes of the coils heat up, turn blue and expand.Comment
