A flying buddy has the 10gx. The idle is good...top end great bit at half throttle the engine will begin to “hunt”. Revs increase then decreases. It’s got me foxed! I guessed that there may be some more crud and dirt in the carb diaphragm. It wasn’t running well ages ago so I did quick field carb maintenance which stopped the dead sticks...could it be something like that again or what?
