Quick Help: Pilot air jet setting? WR400

I assume that is what is causing it, nothing else was changed, everything was just cleaned and it wasn't too bad inside.
Here is the carb, not sure if its FCR 41 but it doesn't look like the stock one.
Pilot air jet on the left..

Another thing, was taking the endcap off the FMF exhaust, every bolt popped like they normally do when they are stuck. Turns out every single one of them just snapped in the middle, half are stuck in the pipe and the other half in the endcaps. Excellent idea to use mild steel on mild steel with shitty hardware on exhaust FMF. Luckily its not too much louder.

I tried ~ 7/8 on the pilot air screw, it wouldnt idle at all. Put it to about 1/2 turn and its ok. My accel pump diaphragm is pretty nasty, it probably isnt working right, so if you give it too much throttle it wants to bog.
I need to find out what model of carb it is, and then I wrote down all the jets and the needle/clip position, etc.
