I'm having trouble with the engine dying with only 4 to5 minutes in the air. The engine is an os 46ax installed in a Hanger9 Saratoga. The problem startred after the muffler came loose on a evolution engine. When I could'nt get that engine tuned, I put the os engine in. It will run fine on the ground and I'm running it 3to4 clicks rich. I pulled the tank and replaced the filter and tubing but it still deadsticks with over a half tank of fuel. I ordered a new tank from Horizon but is there anything else I should look at. IOf anything, I'm getting good at deadstick landings
