As many of you are aware, I won an evo 36 here on stunthanger last month and promised that I would try it out and report back on the result. I mounted it on a midwest magician right out of the box. I used the smallest venturi and the tube type muffler. It was way too fast and seemed to want to run away. About half way thru the tank it started to surge. Ifound that the needle valve assembly from a Tower 40 RC would screw directly into the evo venturi in place of the evo spraybar thus eleminating the remote needle. This seemed to eleminate the surge. I found that a short piece of 7/32 brass tubing was a perfect fit in the small venture thus reducing the venturi to .187 ID. Then I added 2 head shims. The next day I took it out and flew it again and the engine run was just about perfect. The final setup was the above mentioned ,187 venturi, Tower 40 needle valve unit, 2 head shims, fireball hot plug, rich's brew 10/22 fuel APC 10/5 prop ground RPM at 10300. I think it runs as good as anything I own right now. I am very happy with this engine
