Weber DGV has different jets front to back

[mehas240z]

Hello,

 

I took apart my dual Weber 32/36 setup due to an issue with the rear being flooded with water.  I took the rear apart and catalogued the jets and checked the float level.  Then I took apart the front carb and found that the primary main jet was different than the rear carb.

 

This isn't supposed to be like this correct?  I ordered them as a kit so I thought was getting a matched pair. The casings have the same stamping.  I assume maybe that I got one from a different stock.  Maybe one setup for another car/engine?  Old inventory mixed with newer?  I did read that it is possible that the jetting changed across the years...either way, here are my specs.

 

Front

Primary Main - 130

Secondary Main - 145

Primary Air Corrector - 175

Secondary AC - 175

 

Rear

Primary Main - 135

Secondary Main - 145

Primary AC - 175

Secondary AC - 175

 

For what it's worth I have a set of SU's that I need to get the ZTherapy rebuild kit and fix up. I just wanted to know if this happens or is supposed to be like this? Would a half step Jet size even be noticeable in driving?

 

Thank you,
