Mines a 4 stroke. First 4t I've had within about 6 2strokes. It's a bit heavier and a bit more funny about which ways it's stored. But I love it. Ultra quiet, Seems to have more low down torque, frugle to run aswell. All days on 3 litres of fuel!
And it's starts easily enough.
Have a look at a 4-5hp parsun. I'm happy with the brand so far. And a bit cheaper than major named brands.
