3. Coat Throttle Valve Plunger (5) with oil and insert it, rounded end leading, into the inlet hole in Handle.
4. Install a new Throttle Valve Seal (7) on Throttle Valve (6) and insert assembly, Valve Seal leading, into inlet hole in Handle.
5. Encircle cone end of Air Strainer Screen (9) with large end of Throttle Valve Spring (8) and insert both parts, Spring leading, into the inlet hole in Handle.
6. Install Straight Inlet (10) over Strainer Screen in Handle and tighten Inlet between 50 and 60 ft-lb (68 and 81 Nm) torque.
7. Remove Handle from vise and test Trigger. If Trigger functions properly, place assembled Handle aside. If it does not function properly, disassemble Handle to determine cause of problem.
