Good Morning,

I understand Joe's instructions on checking timing; He says to be sure and ground the other wires. my question is, can i just disconnect the other wires between the power pack and coils and follow his instructions, or is that bad for the power pack?

thank you,

seamoors

Never have I said to ground the other wires, nor have I ever grounded those other wires. Don't be concerned about those wires UNLESS you have fuel soaked rags at some area which could catch fire from a sparking plug lead.

What I said is as follows, a copy/paste from my database. And note, if you can't disconnect the "Fast Start" feature from your engine, do not use this timing method.

(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.

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.

thanks for the quick reply. My apologies. it was MarkV_Deep6 who said the following regarding your procedure

Works on a V8 Johnson. Just be sure to ground the plug wires when setting the timeing. (The Power Pak will thank you!)

I know this post is a bit old but maybe still alive.

Can you just set your timing base arm by following this step? And have a good set up of the arm/throttle?

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).

Joe's method is specifically for wot timing. Adjustments to your throttle linkage may still be necessary as per manufacturer link/sync procedure.
