My sadly unfettled 99, it works after a fashion with a bit of persuation. It actually arrived with a mini pump bit no pot gripper. It does need a little effort to get going, both pumping up and a generous prime. Here showing for a tea test. Flame lopsided and it pulses at about 1 beat a second. It certainly needs a complete rebuild at some point. Since the last time I used it it seems to work a little better, if pump gas has been used the wick may have cleaned up a little with being soaked in naptha for the time it's been sat on the naughty shelf.
