Rebuilding Carbs on CL350

[tacks]

Hello All,
I've got my bike more or less all put back together after a complete stripdown and cleaning/repainting. I'm getting ready to put the tank and carbs back on but after taking the carbs apart, it looks like they need to be rejetted as the O-rings are almost non-existent. The main thing that I am confused on is that with the CL350, the exploded view of the carb lists the jet as one piece and then also the brass bits that are called the needle jet set as another part? Basically I am wondering if when I rejet (as I understand it, changing the primary main jet (70) and the main jet (115)) if I will need to replace the needle jets too (numbered 11, 5 and with no number on the link below). This is my first time working with carburetors, and I read the sticky on the basics, so I understand how they work, just not which parts need to be replaced when rejetting. Thanks in advance, I can't wait to get her on the road!

If its the O-rings that are bad, why not just replace the o-ring/gasket set? The set is still available from Honda.

Because since my exhaust and intake are neither stock now, I have a feeling I will have to change my jets anyhow. I'm not sure whether I need to replace only the jets that have the number on them or those and the needles that actually wicks the gas up into the bodies of the carb (needle jets?). Should I just replace the o rings and see how it runs then order jets? This is my first time messing with a carbureted engine ship I don't know if the needle jets have to be changed when the numbered ones down in the float bowl are.

Definitely get the oring rebuild kit first and see where that takes you. Don't jump too far ahead. That might be all you need. This guy has a pretty good deal on o-ring kits

Make sure to get correct kit for your carbs. Honda had a few different carbs on the 350s.

I got my OEM seal kits from my local dealership for about $15 each.

Got the rings, I have one carb that's a 722a and another that's a 3d, but all the internals swapped over fine duo I'm assuming the rings will too.

Check the main jets, looks like the 3d, and 722a differ by a size (68 vs 70).

They may vary stock, but I double checked them, if 68 was standard in one, it was replaced by the previous owner with a 70, all jets match, but thanks for looking out.
