> You couldn't fit a four stroke engine to a leaf blower or chainsaw etc.

Actually not true - you can definitely get four stroke blowers, chainsaws, weed whackers, etc.

Interesting. How do they deal with oil circulation?

Poorly. I had a 4 stroke line trimmer and it definitely didn’t like extreme angles. Back to two stroke I went.

I have a four stroke trimmer that I can change out to a pole saw. I can run it at any angle I've had to so far. It sees some weird angles with the pole saw.
