I just purchased this carb to my sinnis stealth(Same engine as apache).
I dont know to start tuning, in this carb way different over mikuni vm22, starting with size, and screw's turns, its way too different.
Can anyone help at least how to start ?
So far i have 1turn out on mixture screw, but there is alot of exhaust smoke, and it bogs alot.

On minkuni i knew that mixture screw would be fine between 2 turn out to 3 turns out, and then ajusting idling, and it was that easy, but these one, i dont know... :(
