I have a Rossi Pixy engine .12 and seem to have 4 needle settings on it.

The needle that is pointing to the sky is the High end setting

The other 3 not too sure

I have one that is on the end of the slide Carb, one that is opposite to that and one next to that.

I seem to of got the motor running alright its just a bit of a pain not knowing what they do.

Thanks

the one on the end of the slide carb is you low speed needle.

the one that is on the opposite end of the carb is the mid range needle that adjusts the spray bar for mid rev range, which is'nt normaly touched, olny for expert tuners adjust this one, its factory set.

the small screw next to this one is your idle screw.
hope that helps you out,
happy racing
cheers
