RE: engine shutting down on take off
If you would like you can send the engine to me and i will check it over for you. It just might run better than every when you get it back. Or if you would like we could work out a trade. I have 4 OS 46 engines. two of them are set up for a Jett red muffler and the other are for stock muffler or tower.
the two for the Jett mufflers turn 9x8 APC props at 17,300-17,400 and the other two turn 9x8's at 16,400-16,500 on the tower muffler.
