## Discrepancy

(CAN) IAW PILOT " THROTTLE LEVER JAMMING AT APPROXIMATELY 2000 RPM AFTER IDLE FOR ABOUT 20S.  THROTTLE TENSION WAS FULL LOOSE."   UPON INVESTIGATION BY MAINTENANCE, THE CARB WAS FOUND VERY STIFF TO MOVE WHEN DISCONNECTED FROM THE AIRFRAME THROTTLE CONTROL. ON THE BENCH, THE CARB THROTTLE CONTROL WAS INTERMITTENTLY SEIZING. THE PROBLEM WAS THEN ISOLATED TO THE ACCELERATOR PUMP PART OF THE CARB.
