I said I have never hurt any of my engines. I didnt say nobody else has. To each his own but if it were me I would still still get the 56. Kevin told you to get the 50 but not the 56 because four strokes are more prone to damage. The 50 is a four stroke too. Whats the difference? As far as the power thing goes.......Thats what the stick on the left is for. Most LT 40's that I have seen need a little bit of weight up front to balance so the 56 would probably be perfect. Im not trying to start an arguement here but thats how I see it and I dont feel like I'm giving anybody any bad advise.......John
