dead cylinders

[viking]

have 92 Johnson GT200, Fished for 2 days, 1st day motor ran good but the tack needle would make a sweep across the gauge at times. 2nd day was running W/O the tack needle started sweeping the gauge and lost power. turned motor off and restarted, the motor had a miss. while powering up you could feel the motor pick up and drop the cylinders. checked after getting home and found that the bottom 2 cylinders on right side have no spark. I changed the ing coils on the 2 dead cylinders with 2 good one, same problem. I was thinking that the tack signal comes from the power pack and since it was acting funny first the problem may be the power pack. Before I replace the power pack anyone with input on the problem?

Tach signal comes from the voltage regulator/rectifier. Bad juju will happen if you have wing nuts on your cranking battery. Best to spend $1.00 for SS hex nuts and SS lock washers than $1.500.00 in electronics. May be too late as you may have lost a Stator or timer base. If you lost a PP you would loose one side.

Is there a way of checking the stator and timing base with an ohm or volt meter before buying parts.

Yes but you will need the manual.
