Honda 50cc dirt bike carb?

The bike became hard to start and would only run (rough) at low rpms. You can feel a little gas spitting out of the air intake. I turned fuel mixture screw in and got no results.





I took apart carb and cleaned it, plus jets. Didn't help.


I moved pin position down. I got bike to run smoothly after turning the mixture screw all the way in, but only at low rpms.





I am thinking: adjust pin down one more notch, and/or replace pin and jet.


First, I want to see if the float seals off gas in up position. It is not adjustable (but bendable).





Any suggestions?
