I have found that there has been modifications to the piston style and cylinder porting over time which I will document a bit later in another post. You can swap cylinders etc but you must keep the piston and cylinder as a matched set.

Hello Paul and all Boundy Cubs, Scouts and Patrolers,

Paul, very good info for the record!
From what you say - and evidence says - the Boundy engine
was developed and improved over its lifespan.

It appears the Gold Cheetah was introduced in late 1958, and
it was used on mowers and outboards.

I note that this engine was exported too: ...?

I have come to appreciate the brilliance of Boundy mowers.
For me, the Gold Cheetah engine was superior to the Victa design
of the day.

I guess that the Gold Cheetah morphed into the BMS 10 when
the Lawn Scout was retired and the Lawn Patrol was re-born.

It would appear that the significant change, between the two,
was the BMS 10's air filtration system. Brilliant!
Any ideas?
