Pmag electronic ignition

I have been looking to move to an electronic ignition for a long time... even before ordering the engine.  Initially, the credit offered to delete magnetos with the engine order were pretty modest so I decided to simply take them and get flying then evaluate options later.  After 320 hours on the tach and much research I decided to replace the standard magneto on the right side with a Pmag unit using auto plugs.

The Pmag uses the existing drive gear on the magneto to gain crank position information and is mostly a drop in replacement with some minor wiring changes.

One outstanding issue in using auto plugs is the reach into the heads.  My engine uses long reach heads that are about 1/4" deeper.  Pmag reports good success with standard length plug adapters and plugs but other systems specifically call for long reach adapters and plugs so I am looking to find longer adapters and test for myself.

removed magneto ignition harness

removed standard magneto Model 4370

removed magneto drive gear to be used with the Pmag

I used a 3" gear puller to remove the gear from the shaft

imprints from closing up Adel clamps in tight spaces... ouch!

new hat!
