Hard to imagine a 4 stroke weed whacker or chain saw would be much fun to use. Even a backpack 4 stroke leafblower is easily "blown away" by a hand held 2 stroke!
If the tool is on wheels, it's a different thing - e.g. lawn mowers, big leaf blowers, snow blowers, etc., seem to be more pleasant overall as 4 strokes.
When you think about it there are a lot of challenges for the engine designer least of all the climate it has to operate in. Where the motor can be carried as part of the implement/tool it makes sense to use a 4 stroke especially when the task it's required to do is at constant and comparably low revs compared to a 2 stroke.
3600 rpm is easy to do and 4 stokes can last for decades when religiously serviced.
One only needs look at how long a plain silicon alloy bore with a chromed alloy piston that Briggs have used for 50+ years can last. I've seen some survive 30+ years for careful owners.

2 strokes can last a phenomenal amount of work too if you care to analyze their real statistics of use. I well remember when Nikasil cylinders first emerged and a local top pro crosscutter had previously only obtained just 3 months from saws but got 9 months from his first Jonsered 80.
Conservably calculated that was some 300+ million revolutions without mechanical failure !

Power/compactness vs size/weight a 2 stroke wins hands down.
As a former enthusiastic rider of 2 stroke motorbikes, loved the lightness, hated the horrible torque curve. Noisy too, unless you go water cooled and that kind of kills the raw simplicity that is part of the 2 stroke aesthetic.
Only had 2 strokes also and last before going ag on the farm with pop was a Suzuki GT250 X7 I bought new ~'81.
Was courting at that time and always took the long and windy way to see she whom was the wife to be.
Like this but in Gloss Black: (images of black ones seem rare, maybe I should've kept it )

However today what high performance engine today is not water cooled ?
Even the little 80cc scramblers are.
I think the bike I had the most fun on was a KTM 650 supermoto that my son had when away for 3 months at a time doing overseas contracts and pop just had to keep its battery charged.

That thing had real balls and was scary quick from a standing start but man it was fun.
Sad day when he settled overseas after finding the love of his life when working in Perth and told me to sell it.
