Just got around to installing a new mt57 in a plane. Engine was purchased early Dec. 08.
Engine starts and idles great but anything above idle and it miss-fires like crazy. Am running stock exhaust, menz 23/8, peak rpm about 6600. Have tried running remote pressure line into fuselage...no change. Tried every needle setting possible, still miss-fires. Have 7 flights on it and some ground tuning, about a gallon of fuel. Its acted the same way since the beginning.The engine runs the same on the ground or in the air, cowl on or cowl off. I Guess the problem is in the ignition system but i don't know. It runs nothing like the ones in the you-tube videos.
I bought this from the U.S. distributor,
[email protected]...... anyone have any ideas on what's going on with this engine....... or knows who is performing warranty work on this engine.
