Valves were pretty close to spec. A couple exhaust valves were about. 001" - .002" tight, and a couple intake valves were slightly loose. All reset to .016" now.
Cleaning and gapping the plugs. All 4 plugs looked pretty good. Cleaned and ensured gaps were set at .030". This Jeep came with civilian plug adapters already installed which allows you to run cheaper civilian plugs while retaining the waterproof feature of the M38.

Back together again.
The engine started right up and was idling nice and smooth. Now it's time to check timing with the timing light At idle. To do this you unscrew the shielded plug wire on cylinder one and install a non-shielded adapter so the pickup will function correctly on the timing light. After timing is set and distributer is locked down Rev the engine up and watch the timing mark, the mark should advance with increasing engine RPMs. If your mark doesn't change you have an issue with your advance mechanism. All looked good here.

Great to hear that she is running like a sewing machine. Great tech tip on the 24 volt/ waterproof distributor timing process.
Some great shots of the waterproof setup there Hdk! It looks like you have her ready for the show now.
