Bill,

I had high expectations for this engine after all the great advertising that GP did. I could never get this engine to run smoothly. It want's to bog down whenever I change the throttle from low to high and even sometimes on reducing throttle. This engines was supposed to be great for aerobatic planes that needed an engine with great response in any attitude. I have had the fuel lines blow off, tanks burst, I have taped the tanks with nylon strapping tape, clamped the fuel lines, made every adjustment I could think of, tried YS 20/20 fuel as well as a few others. I have never had an engine run as badly as this one. I can't put it in a plane, I am afraid to fly with it. I have had the engine for over a year now so I doubt it is in warranty (I set it on the shelf and tried to not think about it like a fool). Anyhow, I have the original receipt and box, etc. Is there anything that can be done with this engine? I see they have been removed from production.
Thanks...
