Hello
Is it common to have bubbles agitating inside fuel tank when throttling gas engine to high revs?

Yes it is to a degree, just make sure your propeller is well balanced, and the engine has no crank end run out issues from a previous crash.

I also isolate my fuel tank with foam rubber to help dampen tank vibration. If you shake a container of fuel, you will see the same bubbles.

Thanks to everyone who relied.
Will add some more foam to see if that makes a difference.
