1994 Johnson 48 SPL... low speed needle?

[Crashsector]

Good evening all,

I have a very low-hour 1994 Johnson 48 SPL. I did a carb rebuild this off season and now the engine is having a bit of a hard time starting and idling in gear. It will idle great on muffs, it just seems to be a bit off at low speeds.

It runs like a stabbed rat at high speed.

I'm not familiar with these carbs and I can't seem to find a good answer online. Where are my low-speed needles? Here is a photo of the starboard side of the engine:

I think I have found them as A labeled in this photo, but B looks like it could be adjustable as well:

I found the suggested method for adjusting them, just can't figure out which ones they are.

Thanks for any help!

A is the adjustment and B is a fixed jet.

Thanks so much boobie. I ended up about 1/16th of a turn further out on both needles and it seemed to fix the problem. It's still not super smooth at idle, but I guess you just have to deal with that on a carbed 2-stroke.
