Hello Tim

Standard unleaded works on nearly all small engines, but
the golden rule is that all strimmers run on 2/stroke.
Neat petrol will kill your strimmer.

T They aren't all 2-stroke, but the vast majority are. The
T 4-stroke ones are rare, but I know I've seen some in the
T shops.

(Googles) - You're right, Honda do a 4-stroke lightweight engine that
seems to overcome the traditional 4-stroke problems of verticality and
weight. More expensive though, and I can't think of any advantage it
gives you over a 2-stroke, but your point is valid.

Never seen one on sale, mind, nor being used - apart from 20-year old
strimers that have gimble mounted 4-stroke engines and weigh half a
ton.
