Yes, I run Type "F" in all of my larger 2-strokes, they will idle till empty. Also if it is hydro locking your tank may be to high in the fuse, it should be centered about even with the needle valve...it should run flawless when all of the pieces of the puzzle are there...

Thank you for the info. I had someone else tell me that also and someone in my club said to use the "hot" plug. So I did that, and it ran better for one flight and then was back to the same thing. Is there a difference with the four stroke plug?
