New here.
I hope someone can offer some assistance.
Glow Worm Fuelsaver MkII 40 prior to service in working state
Brand new thermocouple out of the box held over a candle flame produces a steady output ~9mV when connected to the valve and after relight will hold supply to pilot open indefinitely (>5 mins). Same thermocouple, valve etc but now heated by the pilot flame and producing ~12mV cuts out at the end of the damped travel for the relight knob!
Any thoughts would be gratefully received.
