RE: .15 ame norvel engine is always quiting on me...
If your NV is almost all the way open to get a run I would guess that you have a blocked ( or partially blocked) spray bar and / or fuel tank tubes ..... give the fuel tank tubes and the engine's spraybar a good 'rod-out / flush out' and also make sure your spraybar's fuel jets (or jet) are totally open and clean.
