Shower of Sparks

[Robert67]

Does anyone have tech data or know the procedure for gapping the points on a shower of sparks system for a 67F model.  That part of my maintenance manual is missing. 
Thanks

In the Downloads section under engines the SoS manual is there.

If you have a newer impulse mag can you just disconnect the shower or spark?

Once you set the gap, pull the plugs, ground one plug and connect the plug wire, rotate the prop to TDC on that cylinder to observe a strong shower of sparks. If no shower, check the retard p-lead on the left mag. In my case I had a short on that p-lead at the mag where it screws in… I thought I had a SOS issue when it was the retard p-lead.

I forgot to mention… disconnect the starter solenoid before attempting the above!

In my opinion Yes, but I’m not a A&P.

Thanks for the great information. I’ll definitely try that out
