Driven pulley spring tension is too smooth and/or damaged. Replace spring.
Symptom: DRIVE PULLEY NOISE IN IDLE SPEED
1. Check slider shoes (drive pulley).
Worn slider shoes (increased clearance between governor cup and drive pulley
sliding sheave). Replace all slider shoes at the same time (slider shoes kit).
2. Check driven pulley sliding mechanism (between driven pulley outer and inner
