That screw controls how much fuel is drawn thru the jet. You do need to go bigger. I had a 47 pilot in the Malossi kit that I still had to ream out.
The air filter is mostly the reason. There is LESS vacuum on the jet so it needs to be larger to flow right.
Every size up will close the screw about 1 turn so try around 45

I just looked again at the carb. I fixed one today on a child size 50cc quad. The OEM jet in it is a 40, and it ran well at 1 1/2 turns out. This one had an adjustable needle on the main but same carb. (with a screw on cap)?

The cc's don't matter this time. It is in the flow in vs flow out. You improved the breathing so you have to improve the drinking... SPEAKING of which.

It's got 45,000 on it so It don't owe me anything. I don't know exactly what/why happened yet. Just have no lower gears. Pretty sure its the td

Raising the needle will compensate some but not much for the idle circuit. The idle must be right to get the rest. The larger idle jet will allow that extra fuel in with the main charge. If it is too small it throws off the rest
