Piston Ring Gap

[Robert Leigh]

I would go along with what Chris says, and have never used slipper pistons, although I am thinking I may try them on my next warm engine build. The rule of thumb I was given 60 years ago for ring gap is 3 thou per inch of bore, and this agrees with what has been said in this thread, and is valid for other engines bigger than Austin Sevens.
