Can you please explain to me a step by step procedure on how to time my motor.I have a 60 hp johnson 1970. the timeing mark is 22 degrees.my manual does not explain in full depth how to time the motor.it just tells me the idle rpm's and low speed carb adj.And carb + distributer synchronizeing. thank you.
 
(Timing At Cranking Speed 4°)
(J. Reeves)

NOTE: If your engine has the "Fast Start" feature", you must disconnect/eliminate that feature in order to use the following method. The "Fast Start" automatically advances the spark electronically when the engine first starts, dropping it to normal when the engine reaches a certain temperture.
The full spark advance can be adjusted without have the engine running at near full throttle as follows. (Your 1970's era 60hp does not have the above feature.)

To set the timing on that engine, have the s/plugs out, and have the throttle at full, set that timer base under the flywheel tight against the rubber stop on the end of the full spark timer advance stop screw (wire it against that stop if necessary).

Hook up the timing light to the #1 plug wire. Crank the engine over and set the spark advance to 4° less than what the engine calls for.
It's a good idea to ground the other plug wires to avoid sparks that could ignite fuel that may shoot out of the plug holes. I've personally never grounded them out and have never encountered a problem (fire) but it could happen.

In your case the full spark advance setting your engine calls for 22°, set the timing at 18°. The reasoning for the 4° difference is that when the engine is actually running, due to the nature of the solid state ignition componets, the engine gains the extra 4°.

If you set the engine to its true setting at cranking speed, when running it will advance beyond its limit by 4° which will set up pre-ignition causing guaranteed piston damage! You don't want that to take place.

No need to be concerned about the idle timing as that will take care of itself. The main concern is the full advance setting.

Be sure to use your engines spark advance settings (22° less 4° = 18°).

Mr. Joe R. Thank you very much for the info on timeing.In the past when i heard that in order to time the motor had to be at full throtle.I was wondering how i could time a motor with it going wide open on the water it would be a chalenge trying to hold the light gettin the degrees that the motor is running at.with your info i realize it is a still test and the motor does not even need to be ran to time.the wide open now makes cents on land not flopping around at wide open on the water.it seems to be a simple task for the most part.my winter project is allmost done with the rebuild.i am waiting for the crankshaft bearings and the shop to finish the bore job.at this point i will have a 40 year old outboard in new condition.the crank i got from you is still in the wrap you sent with it . i was wondering what i should use to clean the crank with you had put some kind of greese to stop rusting can i just use gas to take it off and clean it up nice
 
Cleaning..... Use mineral spirits, then blow dry with compressed air. Note that unless protected (oil/something), rusting starts immediately!

Using gasoline is an excellent way to leave this planet prematurely!
