I want to test the compression on my W5 but my guage is threaded for modern plugs. I see there is an adapter for Model T engines available so they can use modern plugs. Would one of these work? Does anyone have any other ideas?

Hi Vince......

The Star engines are not pipe thread like the Ford T so a threaded adapter for the T will not work.

The Stars use the same plug as a Model A Ford, so one of those would be the same thread as your W-4 W-5.

The old compression gauge that I have has a tapered rubber tip that fits most applications.

I took a old Champion sparkplug and took it apart and welded in a fitting that would fit my gauge and it works fine. The old sparkplugs are three piece and come apart.
