Thanks Max. I’ve just pulled the carby, checked and confirmed the pilot fuel path / gallery I marked up above is blocked, despite attempts to clear blockages with carby spray & tip cleaners. Blockage may be deep within the long passage or behind the Welch plug. I might just use the mower as is while exploring options to clean that gallery (inc removing the plug). Thanks for your help again.
Update - there is actually no Welch plug for this passage. Passage is straight from the pilot jet screw down. I’ll try to use compressed air to blow through this passage.
