Distributor Volvo 240/260 (1266466) (B21F)

A rough idle, odd noises under acceleration or a difficult cold start can point to worn ignition components, and the distributor is then an obvious place to check. On the B21F, carbon tracking, corroded contacts in the cap and a worn rotor arm often lead to a weak or jumping spark. This group includes the distributor cap, rotor arm, safety ring and screw, plus grease – in other words the recurring wear parts that handle and distribute the ignition voltage to each cylinder.
