A friend brought me a carburetor off of a Honda TRX 250TM6 four wheeler. She says she cannot find a number stamped onto the engine, but there is a sticker that says...Engine# TE21E-9003563. The carburetor is a Keihin. Markings on it are KTB, PD, C1F (A) EBK. There is a pilot screw on the bottom adjacent to the bowl, and what I think is an air mixture screw on the side of the carb body. I have cleaned the carb, and cannot find the settings for these two screws. Before I took them out, I closed them all the way. It took just shy of 4 turns to close the pilot, and 2 1/2 turns to close the screw on the side of the carb. Any help would be appreciated.

TRX250TM means that the carb is from a footshift Honda Recon.

The screw on the side is the idle adjust screw.

See screenshot for pilot screw setting. Depends on the year according to the manual, but you should be able to get with range.

screw on side is idle screw, mixture screw is the screw on the bottom near the float bowl.
