I'm looking for a good used 2-stroke hover mower to cope with a steep
grassed bank, but I can't find anything that lists and describes the old
Flymo models. The models that I've seen on fleabay are L38, L300 and
L470, and I'm guessing that the "L" denotes 2-stroke and that the number
denotes cutting width. Are there any other models/manufacturers I should
be considering?
The Flymo website no longer shows the Flymo hover mower I bought with a
Honda 4 stroke motor. Husqvarna appear to sell an identical product.
Strange! Apparently they will work on a 45 degree slop, not that I have
tried.
There are 4/ tools out there now that are 'dry sump' so although they
use valves (like a 4/) they get their (upper cylinder particularly)
lubrication from the fuel, like a 2/.
Whilst that may go some way towards the efficiency (less
over-scavenging), they are still burning oil?

They will certainly have roller bearings for mains and big ends (like a
2 stroke) so only need a whiff of oil. I still find the lack of bore
wear in modern engines astonishing having been brought up in the days
when you regularly had to re-bore bikes and even cars.
My Ryobi 4-stroke power head (for strimmer, brush-cutter, hedge
trimmer, pruner, etc.) seems just to rely on splash lubrication. You
just put oil in the 'sump' (i.e. the bottom of the casing) up to a
(very indterminate) sort of level and that's it. There doesn't seem
to be any sort of pump or oil ways, it must just splash around.
