See full version: 72 Johnson 6hp-Setting points - Please Help
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. [links]
Joe - I absolutely agree that your advice is per the factory specs, but I have a question that you might know . my OMC dealer mechanic likes to set points on the old magneto motors at .022. He says the points tend to burn less at the larger gap.
The manual will cost you less than 10 gallons of gas (not including oil) and probably save your butt many times that over time. here
Guys. I need some help. I need to check and maybe set the points on my 72 6HP seahorse. Its a dog. I cleaned out the carb, (did not rebuild yet) checked spark, and all is good. other then it will not wind up all the way. seems way off. I am a total noob when it comes to motors

It's for a 9.9 but i think they are basically the same as far as the ignition system goes.

Depends a lot on Model number. i.e. points or electronic ignition? more
If it is a universal magneto motor from the 60's-70's with two sets of breaker points, the ignition timing is set by the breaker point gap. Usually gapping them to 0.020" will produce an acceptably running motor. There is another adjustment for when the carb starts to open up as the armature plate rotates as the throttle is opened. Usually there is a mark on the plate for that throttle cam timing point.

The timing of that engine is set by the flywheel key aligning with the crankshaft, that is. if the key in the crankshaft is aligned with the flywheel and IS NOT sheared, the engine is in time. The only other requirement is that the points are set properly as follows.
Respectfully I disagree with Eddie. Pulling the flywheel is pretty much a PITA. If you gotta pull it off, replace them both. Your not talking about boat bucks here. I have never, ever just changed either the points or condenser, without replacing both. more
A couple of tips about points and condenser. Replace
I usually never change out the 'condenser' (capacitor) on the Evin-2, but have had a few 'coil failures' over the years. Ive had/have several Evinrude-2's. Its a GREAT little OB.
Since Bombardier of Canada bought Evinrude, parts are widely available, even for units made in the 60s.
When changing the points for the first time on the Evinrude 2, I strongly recommend to take a few digital pics of exactly how the points assembly is in its 'final form' on the base plate BEFORE you remove it.
Replacement points are usually in 2-parts and if youre not very careful and not assemble them EXACTLY as the 'final form' that you saw, or how it looks in your pics you will be shorting the 'positive side' of the breaker points directly to ground . the problem area is: which side the 'spring' is attached to the points electrical connection with the screw that tightens to the 'base assembly' of the breaker points. The spring carries voltage.
