Good morning afflicted and welcome.
1) Can't gain much information (if any) from the engine numbers, except the engine was built 6th August 1991 (Code 910806 in YYMMDD format), and are required to gain service and parts manuals from the Briggs and Stratton Website. So, at a guess, your Rover could have been built between 1991-1992, but only applies if that is the original engine. :-)

Specific manuals for your engine are available from the link below:-

2) As for this, Agent Mulder would say "You are not alone".

I'm relative new to the forum, but the assistance from members is great.
Hope this helps.
