Differential cylinder pressure tester

Just curious, what is everyone using for compression testing the CC340 with the 14mm Denso plugs?

I took the guts out of a spark plug and welded the quick coupler to it.

Thanks Chuck. I do not have access to a welder but know I can buy an 14mm adapter.

My question was more towards the make and model of testers as most descriptions of compression testers mention an 0.040 orifice that is required for various types of engines.

This tester has worked well for me. I turned a stub for the car-plug threads and slipped on an O-ring.

Thanks Dan. I have looking at ATS as they have a sale going on.

I'm going to try an OTC 5603. Looks like it will work
