Default O.Stz .12 QUESTION ABOUT MRN

I bought an O.S 12tz off a guy at the track and i think he was playing around with the mid range needle. Can anyone tell me where i should have mine. Which way in the carby do the holes in the needle face? I want to put it back to the factory settings. I've looked for manuals but couldn't find one for the TZ.

Thanks in advance

Needle Settings:
High Speed Needle:1 open from closed position as per page 18 of manual.

Mid Speed Needle:The head of the screw is flush with the carb body as per page 25 of manual.

Low Speed Needle: Head of metering needle screw is flush with the ball link body as per page 25 of manual.

Idle Speed Screw: This is set so the slide is still 0.5mm open when closed as per page 18 of manual.

Those are default. You have to determine optimum setting for your area.

I think that manual is listed on the OS web site in PDF format
