I'm just sending off my last 2 - stroke ( OS 1.60 ) to it's new owner today. I have tried and tried to get comfortable with 2 - stroke engines ( cost, simplicity, etc. ) but I keep coming back to 4 - strokes ( I have 10 ). Engines are the most satisfiying part of the hobby for me and if an engines doesn't have a zillion parts flying around inside and have that putta putta sound I'm just not happy.
But I'm sure the 120 AX is a very fine engine, just not my cup of tea.
