Found this cutie today with a nice price tag, it was an exact fit in my saddle bag, back home i found the filler seal could scratch a diamond, pump again with new seal and it blew like from the jet with "closed" valve! OK - the needle, hmm - no tools in the right size my other fettled stoves had 4mm tool size on jet and nrv. Using eyesight to estimate this one is 5mm, making a new tool and, then needing 2 tries before getting the pricker high enough to allow closed valve as I didn't remember the exact turns before installing the needle and too lazy to trawl around CCS to find the instruction. It came with a priming bottle that use to be tagged more than half the price I paid - and three new Optimus stove prickers and jet+pricker+tool that seems to fit my Optimus 930A lantern. My 2 smoke detectors upstairs are old but both worked perfekt today as I fired up before opening the front door. Still a small leak in the NRV but it works so that's another days job.
