What is 23L? Im new…

Main 145?

The one that’s on my table by itself is the main. The other one is inserted in the carburetor the hole is significantly smaller. When you say large headed are you referring to the hex Version? I mean she’s running great, it’s amazing what happens when you ditch the in-line fuel filter and perform a carburetor clean out. But I’m like you, the main says 45 on it, but the little air version must say 4.5… but my old ass I can’t see. (43) LOL. But the slide looks a little worn, because aren’t they black stock? Because you could tell where it’s been rubbing inside the carburetor the black color is worn off down to silver. I gently took a 0000 Wool pad to it it’s sliding better than it was when I started to clean out.

The two jets you show in your picture are air bleeds for the pilot circuit.  They are the corrcet size.  The larger jet is supposed to be a #230 and I believe that you have a #230 but the stamping for the "0" is not complete.  The smaller jet is supposed to be a #45 and I also believe you have a #45.

If you wish to double check the size you can use the shank of a drill bit to verify the holes are in the ball park.  

The #230 will have a hole that is 2.30mm.   That's .090" so a #43 drill bit will just fit and a #42 drill bit won't fit.

The #45 is 0.45mm.  That's .018" so a #77 drill bit should fit snug and a #76 drill bit won't fit.

Good luck, Mike
