Hi everyone, I own a DF2.5 short shaft. I disassembled the carburetor in order to clean it, but when I started to reassemble I noticed the exploded view on a website (mistermarine.it) was different from another website (brownspoint.com). In Mistermarine's website, the pilot air jet is 135# and the main air jet is 170#; in Brownspoint's website, the pilot air jet is 135# and the main air jet is 145#. I know the size can be different for differents Countries, but the most different thing is the position of the jets:
- in Mistermarine, the main air jet is element n.17 and the pilot air jet is element n.18;
- in Brownspoint the main air jet is element n.18 and the pilot air jet is element n.17.

I looked into the service manual and it confirms Mistermarine exploded view.
How do I have to reassemble the jets, in your opinion? Thank you!

PS: I measured my jets, the pilot one is 135# (1.35 mm) and the main one is 145# (1.45 mm), according to Brownspoint. The only doubt is where I have to reassemble them.
