blowerz you start with the upper needle first,then lower,upper needle counter clockwise
open it up 1/8 turn at a time till it runs smooth if that doesnt work turn opposite way,lower needle on side of carb the bigger screw i have always left at stock setting flush with outside edge, sounds like it is set to a rich setting no worries of hurting it then ,

Ight guys i have just had a whole new like carb block put on my mt2. and it starts perfect 1st time. but when rev it goes tiny bit and spits quite bit of fuel but u can full throttle it and goes dead slow. only tried this 2wice or it would damage engine. so is it just a case of puttin it on a block and tuning the low speed needle to get it moving quicker then move onto the high speed needle??? by the way using a t-15 engine.
