Hi all! I'm having some problems with my engine after having a bit of a crash... The engine still starts as well as it used to, but I can't get it to rev as highly as it used to. I used to be able to get about 11,500 out of it and now only about 9,500 or so (thats a guess as i dont have the tools to measure it). Also it seems impossible to get the perfect mixture.. It used to be easy to fine tune the mixture and there was a very obvious point where the mixture was perfect and the engine revved nicely. but now when i adjust the mixture I dont seem to be able to reach that optimum point. it kind of goes from really sluggish and wet, to working ok but not brilliantly, and then the performance stays the same for about 5 clicks, and then suddenly becomes to dry and conks out. I'm not sure whether this is due to a bent needle or if the engine simply wont rev past about 9500 due to some damage elsewhere, but I've removed the needle and inspected it and there is no obvious damage at all. What can commonly cause a problem like this? The plane did suffer a reasonably serious crash, but it seems odd that it starts and runs smoothly, just that it refuses to run at the speed that it used to... Any ideas at all would be very much appreciated... By the way it's an SC 46 2-stroke.

Thanks guys!

Mike
