Hi twinshock325 Thanks for your replie I think I seen these specs on an old post but the PHBH and the PHBL carby run diffrent emulsion tube and needles PHBH run an X needle and PHBL run a D type needle I am unsure what the diffrence between the two carbys are but the are small differences between them. Is it possible two cross reference the emulsion tubes and needles to the other styles. I could start buying needles and emulsion tubes until I get the right one. I have an idea on tuning needles but emulsion tube are a diffrent story I can not find any info on selecting the right one. Dose any one know how to select an emulsion tube. Thanks Matt l

Hi there I own a Bultaco Sherpa T 250 M49 and I have fitted a new dellorto PHBH 26 BS and I am wondering if anyone has a known and tested jetting specs for this bike I have tried to contact various company's but with no success. I would like to know which of the following 1. Atomizer 2. Needle 3. Pilot jet 4. Main jet I know each bike is different and will require a tune specific to the bike but a good base jetting will be great to know as a starting point
