stalling on take off

[scootcoot]

Decided to run my 28 dell carb open mouthed ,previously was using a ramfilter ,uped the main jet accordingly, problem is once it starts it hesitates when the throttle is pulled and wants to stall so the revs have to be kept high when i pop into 1st and try to take off it stalls ! would this be to do with the pilot jet or maybe the airmix screw ? 50 pilot, screw 2 turns out.

Well after p**s farting around all day trying all different combination of atomizer and needles i finally got it to take off without stalling with a AV268 atomizer and a X13 needle on top clip seem to have done the trick !
