Older. probably, and 2-stroke which necessarily burn some oil and
produce blue smoke. Another reason why I like my 4-stroke Ryobi.


Does such a chainsaw still exist?

all my saws have been 2 stroke
power to weight, mate.



Well I know that. That said, Sthil do make 4-stroke strimmers/brush
cutters (that run on two stroke fuel) so not impossible, but I couldnt
find any Ryobi ones. A quick search suggests that other brands *do* exist.

I had a Ryobi 4 stroke combi / strimmer power head for a bit. It was a
pile of crap alas. (power output was not that good, it did not run well
at certain angles (typically those required when hedge trimming), but
the biggest weakness was the plastic components in the valve train that
made it almost impossible to tune and keep running reliably. Replaced it
with a Stihl KM 94 RC-E KombiEngine, which is vastly better in every way.
