Does anyone know the factory needle settings for the TZ. I'm just having a bit of trouble getting it tuned right so i want to start again.

When i bought it off my mate the mid-range needle wasn't flush with the carby and now when ever i get to mid/full throttle it flames out. I'm hoping it's because of the mid range needle not anything else.

Every other motor i have they say keep the mid range needle flush with the carby, is it the same with the TZ?
