PZ27 carburetor jets....

im having a really hard time understanding the jets on this pz27 carb. when i look up the bigger sized jets i find the sizes needed 130 main and 17.5 pilot.....but they look nothing like the jets on my carburetor. Does anyone know 1. where to find the jets needed to make this carb work on my engine? and 2. if these carburetors come with different style jets?
I too have a brand new pz27 and curious about any advantages of it over a 22 mikuni in a tillotson212r build with black mamba Jr cam? The pz27 uses keihin pilot jets and my mikuni main jets seems to fit.
