ECHO CS-352 ES Chainsaw Carburettor WALBRO WT-991

Walbro WT-991 carburettor the Echo CS-352 (ES) chainsaw. The carburettor controls the ratio of air to fuel entering the engine — when it fails through wear, blocked jets, damaged diaphragms or a cracked body, the engine loses the ability to run at the correct fuel mixture across the throttle range. Symptoms include hard starting, hunting at idle, stalling under load and poor throttle response. Where individual components are too worn or damaged to rebuild, fitting a complete replacement carburettor is the most reliable way to restore correct engine fuelling.
