A question on Les Andrews's ring specs

[Joe K]

Briggs & Stratton air cooled engines (warmer cylinder) specify 0.007 to 0.017 range for all sizes.

Been like this for a long time.

You may be fine where you are.

Here's the B&S Service Bulletin from the 1950s. http://www.oldengine.org/members/murphy/Briggs%20&%20Stratton%20Repairman's%20Handbook.pdf Page 50 of the book.

There are other numbers given for feeler gauges/piston clearance.

Not sure if this is an apples to apples comparison that will work for something like the Model A engine, but what a book!
Thanks for sharing that with us.
When asked I have always told folks the engine is like an old Briggs and Stratton, but I was just trying to give them a sense of how different the modern engine is compared to the one in my Model A.

I liked these engines but had no idea how well you could rebuild them.
