Never did get a reply to my question. I wasn't trying to be a smart-alack. I guess it was supposed to be 'BDC'.

My setup: Mity Vac, air tool fitting, Snap-on compression tester hose.

The sparkplug adapter you are using are like the ones I make and use, they will leak around the threads unless the compression ring is still on the plug, seat it tightly with a compression ring on it and it will seal properly.

How do you knock the center out of the plug? I've smashed two plugs and still haven't been able to get the center out.

That ceramic part is actually held onto the metal base by a shoulder that is machine rolled into place against the ceramic center portion. It is very easy to grind off that rolled over portion with a cut off blade on a mini grinder or it can be ground off fairly easy on the corner of a bench grinder wheel, once ground off the center portion will just fall out of the metal base. I have made many of them, many members on here have one I made.

Perfect! It's out now. I've been beating on that thing for 40 minutes. Google didn't even help, so I guess you're smarter than google.
