@Charlie Abbott They’re available, certainly, as one of the more common burner patterns and outputs. Ebay’s probably the best source. Try seach terms of ‘acetylene lamp’ and ‘carbide lamp’.
Thank you, I could kick myself, too heavy handed Whats the best way to clean them out ? All the best Charlie
Well, they’re not meant to be poked at with a pricker, because the ceramic component the very fine jet orifice (or orifices, there are often two) is formed in is quite soft and could be damaged. Carbide lamps incorporate a felt filter to trap water droplets in the acetylene generated and any stray dirt particles, so they shouldn’t block. Carbon can form at the burner outlet in some situations (water drip turned too low, gas generated below optimum) and to remove that a number of lamps had a small wire brush as an accessory, such as this one in its own stowage loop on a Reimann carbide lamp.
