(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 temperature.
The full spark advance can be adjusted without have the engine running at near full throttle as follows.
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).
Rig a spark tester and have the gap set to 7/16". 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.
I don't know the full spark advance setting your engine calls for, but to pick a figure, say your engine calls for 28?, set the timing at 24?. 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 own engines spark advance settings, not the one I picked out of the air here in my notes.
I am missing something serious here. On my motor I have wires running up under flywheel on port side on starboard side I have an arm that attaches up under the flywheel with a locknut and thumbscrew. Question #1 If the arm on the starboard side is moved forward to contact the screw under the flywheel and wired there what good will it do to turn thumbscrew as you have immobilized the arm. Question #2 Is moving that arm to contact that screw is that full advance. It sounds easy when I read it when I apply it ain't gelling. Somebody give me a clue here.
There is a rainbow here, my starter had a bad top bushing and drive I figured would make it this year. It didn't . Had to get another starter buy it crapped out on the landing and not in the middle of the lake.
