I have a Briggs engine on a mid 1950's ROCKY riding mower with a Briggs engine beyond repair, the Briggs I D tag says it is a Model 1600-127 serial number 5610029B. We need a replacement motor for My Grandson's 4-H Americana project. I have seen old Brigg's engines listed with model,s B, S, FH/
My question is what model does the above mentioned Model and Serial numbers equate to? Thanks .
