Didn't want to hear about those bad bearings Skypilot. Makes me wonder about installing the Evo .46 in my Aero Commander.
Is anyone else out there having Evo .46 problems? I may send them back to Horizon and get something else.
I disagree with Skypilot on the fuel filter thing. I've seen them clog up with junk that would normally go right through the carb and personally, I think they cause more problems than they are worth.
Holding the airplane up vertical will allow the engine to lean out and quit, if it's going to.
Just hold it up straight vertical at full power for a few seconds.
The air leak you had may have been from a hole in the fuel intake line in the tank and you might want to make sure the tubing does not have sharp edges as I mentioned earlier.
