In reply to TobyA: 'nearly 20 years'
Me too, they're bomb proof...only use it as 2nd stove now because it clogs unless you only use coleman fuel. First stove is now the newer version with the Shaker Jet. Fine on lead free (and I'm told virtually everything else) so costs very little to run...getting more expensive all the time tho'
To the OP - It is worth investing in the maintenance kit if you rely on it in the mountains...'o' rings, lubricant grease etc Learn how to strip the stove and re-assemble - it is simple once you know how.
