Description
Overview:
This Genuine Part gasket and diaphragm set is designed for Husqvarna K760 and K770 petrol disc cutters. It renews the carburettor's sealing surfaces to restore steady fuel metering, easy starting and clean throttle response.

It directly replaces OEM number 506 40 99‐02 and is correct for machines fitted with the Zama C3‐EL53A carburettor. A sound seal between pump and metering circuits helps maintain idle stability and cutting performance under demanding site conditions. Suitable for routine servicing or fixing faults such as hard starting, erratic idle or fuel seepage. Designed for a straightforward fit with standard hand tools to minimise downtime.
