I have removed the magneto from my power unit and gone through it and it now produces spark so I need to re-install it but I am not sure how everything lines back up I know that inside the mag is two gears to drive the rotor and I havent a clue how to get those in the right spot as well as reinstalling it on the engine. can anyone help?? I am of the understanding that the engine in the H tractor is the same.

Thanks for any advice.

on the end of the plastic gear where the rotor fits are the letters R and L, line up the R with the tooth on the drive gear which has a bevel at the end of the tooth.

elemetary. the spark occurs when the points open so the rotor must be lined up with a plug terminal at that point. Then find top dead center on compression stroke for #1 cylinder. Set mag so points are just starting to open, stick wire for #1 in hole that roter is pointing to, (should be two o'clock)then countinue clockwise, firing order 1,3,4,2
