PZ26 carb tuning guide to use for RXB150

Found this while trying to find info about the carb on my Orion RXB150. I am still a bit confused about this carb. It is a Mikuni, but the Keihin PD is mentioned as being the same. This site is yet another brand, apparently used for racing...Walbro.

http://www.ccwthariders.com/uploads/...ing_manual.pdf

In reading it I think I may need to change my pilot (slow) jet (still need to verify by adjusting the pilot air (fuel) screw).

Does anyone know if these carbs use the same jets as the VM series? If not, then where do you get jets for them?

Please fill me in.

Looking around some more wonder if a Mikuni VM22 (that is a 26mm) would fit and would be a better carb.

I tried looking there, but nothing for PZ26. There are about 7 pilot jets that just have part #, then the VM ones. I guess I will have to contact them.

I also just sent a note to Orion, as surely they have a bunch of jets that fit.

Can you post a picture of said jets? Some different measures will help as well to identify the jet type.
