G'day Mod BB, MF and LRT

I feel the 4-stroke mower makers are correct in saying their
engines will operate on any 'safe' slope. The safety factor goes
to the safety of the user; not the engine.

It is no surprise cutters/trimmers have won this use application anyway.
4-stroke engines that run clever reservoir/pump designs
can accommodate any angle of operation - just like in aerobatic
aircraft engines, I guess?

Cheers
