You may be able to put a washer underneath it.  Raising the needle allows more fuel to pass = richer.

Rich is raising the needle, and lean is lower. To raise it you can use tiny washers or "O" rings. You can also cut your own slots using a dremel tool.

..what I had to do with my stock carb was to shave a bit of material off the needle's black nylon retaining clip..

..i also filed a small amount from the top of the needle's head..

..then I filed down a small washer to .025"...this washer i placed beneath the head of the needle, then carefully installed the nylon retainer...

..don't force the retainer...if it won't turn to lock in place, file a little more off either the washer or the bottom of the retainer...

..i'm not sure what works on most gy6 engines...

..my engine is a CK139 QMB-2...

..my carb has CK50QT-5 on the diaphram cover...

..my scoot seems to require a larger main jet than most others, with the K&N filter, it requires a 102...

..I believe that I might have a different build than some other A50s around...

..and i'm almost positive it's waaay different than most chinese ..

..what I have been able to find out by searching those numbrs is, that my scoot has a different piston and rings than some others..
