Fault diagnosis Symptom/fault Remedy Engine fails to start 1. Carry out the following operations: 1. No fuel to carburettor: - blow fuel pipes, clean fuel tank, renew fuel filter; - blocked fuel pipes or fuel filter; - clean filters; - clogged carburettor or fuel pump filters; - check pump operation and renew any damaged components - faulty fuel pump 2.

Main bearing knocking Typical knocking or thumping noticeable at sudden throttle opening at idle which intensifies with higher crankshaft rate. Excessive endfloat of crankshaft causes sharper irregular knocking, especially noticeable during smooth increase or decrease in crankshaft speed. 1. Early ignition 1.
