Yz 125 carb issue

So i’ve been battling carb issues with my 02 yz 125 for a while now. recently took the part again because bike kept stalling out every now and then if i️ was pinned on the track or putting in trails it would just happen. every spark plug pulled was great color so i️ figured it was float level being off. raised the float quite a bit and richened the needle by one level. now the bike refuses to hit power band and seems to be running so rich all the sudden. any ideas for when i️ pull it apart again tomorrow? very appreciated.

Only ever change one thing at a time on your carb. Is it a pwk or pwm?

Make sure your fuel tank air vent is working properly and allowing air into the fuel tank.

Make sure the screen on the needle and seat as well as the screen on the fuel petcock are clean. Clean any dirt and debris from the fuel tank.
