Just adjust the idle speed control/Fuel air screw located pointing downward on the bowl of the carb,Just start the engine,idle up high and turn the screw until it levels out and runs smooth.

Careful with the high octane.. That can burn a hole in the piston..
It might be fludding.. At the bottom of the carb should be a bowl.. One bolt at the bottom.. Take it off and clean it.. Spray some carb cleaner up in there where the float is..
If that dont do it --
Maybe the float is bad & taking in fluid..
If it has sat for long piriods of time - the carb might need to be cleaned & rebuilt..
When gass sits in there for a long time it shalacks and wont work correctly..
Pop off the carb & take to your local small eng shop. Shouldnt cost to much..

check fuel flow from the tank out of the fuel fuel pipe allso check the float level sounds like its running out of fuel then its needing fuel .at idle it can get some fuel but at fast no fuel try that mate

If it starts lightly smoking black smoke at high RPM it is flooding or getting too much fuel. The float is leaking you may have not set the float height correctly when you put that carb back together. Or the needle and set could be bad.
