4th ring

Post by Johnno »

Hi all,just purchased a set of rings for my side valve MM.I take it the bottom ring is just to hold the piston steady.? Mine has dowels in the bottom ring lands. Should there be a correct way to gap the ring?the dowel is approx 4mm so impossible to gap to 2 thou.4 ring pistons.
Definitive answer is,,,
Power to your Pistons,Johnnydoome.
