Just a heads-up for those who may be interested.
Handy item to have for sure, kind of hard to find locally. I did get one years ago online from some auto supplier.
Thanks for the post Charles.
get 4, screw them in and then put modern 14mm plugs in and see if it runs any better!
Use the hottest plugs you can find.
My compression tester came with the adapter.
One advantage of have one for 35 years.
I clicked on "Add to Cart" and it doesn't work!
"Email to Friend" does not work either!
That's just a .JPG image, (photo), that I posted, not an actual link. Here's the link: https://www.modeltford.com/item/5201CAD.aspx
I've had one for years. If that's new to Lang's, I must have gotten it someplace else.
The actual catalog listing says, "For use with compression tester only." I take that to mean the brass won't take the heat of being used as a spark plug adapter.
Brass will in fact stand up to plug duty. I have made a bunch of these adapters before I sold my lathe. I always bought 1/8 X 1/2 pipe bushings from Lowe's and drilled them up to accept 14 MM tap. I have been running them for years as have a number of others that I made them for. I run them in aluminum heads as well.
Thank you for the heads up on the broken link. Jim is fixing the issue. Yes Peter, these were made accidentally in brass and they make a good use for a tester, but we do not recommend brass as a regular 14mm adapter for plugs.
The brass is most likely stronger than the aluminum used in H.C. heads.
I was making a funny!
I found some take apart old plugs in a antique store, took one apart and looked good inside, but do they have a heat range or are they all the same, thought it might for tractors or old engines. most were champions but some different
They have a heat range as defined by the length of the electrode. The longer the central electrode is, the longer it takes heat generated in the combustion chamber to flow through the electrode and reach the metal body of the plug to dissipate (such a plug would be a "hot" plug, shorter electrodes cool quicker and therefore are "colder" plugs).
Plugs that are the same brand and length will have the same general heat range, but different brands can be the same length and have different heat ranges due to differing manufacturers designs.
Sometimes I'm dense
Thatís OK Jerry
Just a Little News England humor that is so dry you can hear it crackle.
It crackles because Fred ran out of Jelly to go with the other stuff he uses !
I'm a little slow tonight, Fred. Took me a minute to catch it. Hope you're staying warm tonight.
