I have circled the throttle lever in the pic below...my question is this, Is the plastic bushing that rides in the slot SUPPOSED to be flat on one side? looks like wear.but I'm not sure. I'm having issues getting the motor to start without forcing the throttle open. I also cant get it to hold a proper idle. Wide open runs fine, Seems like a low end range issue, it just settles down and then starves out.
