GTS needles

[Fabio]

    So I recently started up my GTS engine with its twin
HS2 carb setup. The engine is running very rich even with the jets turned all the way in. Does anyone perhaps know what setup I need to use there? I am using 0.09 jets with GY needles. Info on these engines are really scarce. I have added a pic of what I have found, but not too sure if this info is correct
