Title: B33 spark plug
Post by: bruce.craig on 31 Aug, 2022, 15:35
Folks, I would appreciate any feedback and/or recommendations for the spark plug for my 1952 B33 plunger that I am currently rebuilding.

My research leads me to a NGK B6HS however I would be interested in any feedback.

Cheers for your help.

Bruce

I run my B33 and M33 on Champion L10. Not sure of the modern equivalent I think it is a L82. As an aside I have been running my B33 on a pink Lodge plug that was in a B31 that I got from a garden after laying there for 50 years.

I have a 53 B33, runs very well using the Champion idie uses. I've no reason to use anything else. L82C. There is also a new, modern part number on the little box: 811. Here in the states, usually listed as a small engine plug like lawnmowers, etc.
