leakdown test

[Russell in Tulsa]

Was reading about the cylinder leak test and saw the US General tester but it comes with 12mm and 14mm sparkplug adapters. Can an adapter be found to fit the "A" head and adapt to the 12 or 14mm as supplied by the tool?

I got several of these, one for my compression tester, one for my leak-down kit, one to keep in my tool box, & gave one away to a friend.

Snyders:

Use these on your Model A if you want to use modern 14mm spark plugs. Just screw these into your head, and you can use any 14mm spark plug. Also available in singles for compression gauges. U.S.A.
