Wow, no one is going to argue with 3 moderators! They have it right. But I'd also add that a 1.8 fourstroke pretty much equals a 1.2 two stroker. That would be my preference before switching to gas.
From a practical point, when you get to big 4 strokes, the cost of fuel becomes an issue for me. A Saito 180 is pretty thirsty. That is why I am converting it to gasoline.
There are so many small gassers out there now, that a big 4 stroke just does not make sense for me, although I love the sound!
I am playing with several 4 stroke Ryobi gassers, and am looking for a Stihl 4-Mix for converting.
