I have a tt.42 gp on a morris knife edge. I have a lot of problems keeping it running smoothly, I have the fuel tank mounted outside the wing opposite the engine at the same level as the carb but it seems as if the fuel is not flowing properly. I have adjusted the high/low adjustments screws, and moved the tank to different positions, yet I keep having a problem keeping it running smoothly, if it decides to stay running at all. maybe if someone else has this engine setup as a side mounted engine on a plane like this you could suggest something.??
