HI All Glad I found this site. I am a newby. Have a Coleman 502 but havent had any of these that I found recently at an estate sale: Svea 123 (2) Svea 123R, Primus 71 Optimus 8r and Optimus 99 all in one box! Svea 123R fired up (see pic) but after I shut it down it kept ooozing fuel out of the jet. Any one know why? Please advise. Also the primus 71 fired up but weak flames. Thanks in advance fo any help.
