I noticed that when running at full throttle ( initial run in) that there is a steady line of bubbles in the fuel line. When I drop to 3/4 throttle the bubbles go away.

I have no room to insulate the fuel tank from vibration in this Superstar 60 so I am wondering if this is one of those normal things unless you buy a certain kind of clunk or something.

Also I set up the initial rigging on the throttle to have full operation from the servo, from full open down the throat of the carb to full closed down the throat. I have noticed that no matter where I set the trim I can shut the engine down with the throttle, even if I set the throttle trim to half throttle..

What am I doing wrong please? ;(
