I just received the rebuild kit fir my 135 with Perkins AD3 152 engine. Sleeves and pistons are Anglo, made in England. Pistons are 3.595,
Sleeves are 3.610-3.615, that's .015 to .020 clearance. Is that correct, what are the acceptable tolerances. The book says the top ring should
have 0.014-0.027 ring gap. These new rings have .039 ? Quite a difference it seems like. Dick
