Re: Model and Year by Serial Number
6.5 hp ??
Unless its pretty old I think you will find that it must be a commercial model from 1981 to 1993
If so you are looking for one of the following model numbers .. on the clamp bracket or a core plug on the engine power head
7RSF / 7RSLF 1981
7RSQ / 7RSLQ 1982
7RSV / 7RSLV 1983
7RSP / 7RSLP 1984
7RSH / 7RSLH 1985
7RSB / 7RSLB 1986
7RST / 7RSLT 1987
7RSY / 7RSLY 1988
7RSA / 7RSLA 1989
7RSK / 7RSLK 1990
7RSS / 7RSLS 1991
7RSG / 7RSLG 1992
7RSW / 7RSLW 1993
