If memory serves me correctly this engine has an 8cc tank, and on 10-22 power master fuel how long should it run? Thanks

MM,
ISTR getting about 2:10-2:25 on mine just before it declared itself too old to run any more. My 5cc Babe Bees get about 1:45.
My youngest son says the GB took about two pukes, and the BB is one puke. He doesn't fly for that reason, and never liked the noise either. I should have started with electric. Sadly, my last video of him flying is as an 11 yo, in which he is crying by the end of the flight. Talk about a guilt trip! "Fine kid, no more for you...but I'm staying in the hobby," I said.

Maybe I remember the Babe Bee time incorrectly. This is on 25% nitro:

On 42’ lines about long enough
On 20’ lines way to long
Never timed one with a clock

I'm not certain one can accurately answer that question without knowing what you have. Early Golden Bees had a single ported thin walled cylinder. Later variants used dual ported cylinders. The difference in run time just in this factor is almost a minute. In addition, the early tanks used small venturi and small backplate intake holes. This increased run time but seriously had the engine down on power. Using 10% nitro in a older Golden Bee would be substantially down on power.
