Ok fellas, here are a few more questions. I am working on an old stove my father got from an older plumber I know it’s older than myself (1964) maybe almost as old as my dad was (He was born in 1927). It’s an AGM JiffyKook No.15 with a square slotted burner. Anyway, Fount is solid (It’s nice to be in Montana, very little humidity=little to no rust) I have removed and cleaned the NRV/check valve=good Pump is working and seals when screwed down=good Carburetor valve? (The one on the fount) is working. A little soak in mineral oil softened up the tank cap seal=working. Stove is holding pressure=good. There is a steel washer under the air screw? on the fuel cap. QUESTION 1: Should this washer be a leather seal, or brass washer, or is the steel washer correct? I pulled the generator (Oh hell…..no generator spring) Question 2: Anyone know where a replacement may be found/made? The end of the generator rod needle is ground down to a point I think the actual needle is missing, and don’t know how it was originally attached? I recall, back in my youth, like when I was 12-15….I think I’m the dirty dog that filed the tip of the rod down as a “fix” for the broken needle. I think it probably widened out the jet. Hey, I was young and dumb. The needle point does close the jet, but….the jet hole looks mighty large compared to my Coleman 424 “Duel Fuel” stove. Looking at my Coleman, I might be able to modify a Coleman generator if need be. The threads on the AGM jet look finer, but maybe I could shorten a Coleman generator tube/spring and needle, then thread them to the AGM specs If anyone has any ideas, or maybe a place to find parts for this old workhorse stove, I welcome the input. Thank for any and all help, and advice.
If you want humidity, move to the very NW corner of the state Pictures might help. You probably wont find parts, but making them is doable usually, Coleman parts can likely be fabbed to work. I just made an AGM generator needle fit in a Goldberg stove.
@Majicwrench Yes, I should have specified “on the prairie in Montana’s “Banana Belt” the humidity is low”. Libby area….not so much I didn’t think I could post any photos without subscribing (I don’t do automatic renewals, otherwise I would subscribe) It looks like I might be able to now? I just need to haul out the stove again.
You can post pics, and we love pictures. The Coleman Collectors Forum may be a good source of ideas too.
Ok, Thanks. I’ll have to get it out again. I’m thinking I can find a Coleman or two at the pawnshops to use for parts/experiments/donors, and for less than the cost of a new generator.
Ok guys, I have the AGM JiffyKook No. 15 up and running. I know for a fact it hadn’t been fired in over 50 years. I used a Coleman generator tube assembly that I modified. I first turned the nose down on the jet to fit into the AGM manifold. Then I cut the generator tube and spring down to length on the valve side. I then threaded the tube with a 5/16” 40 tpi die (I would have liked to have used a tapered pipe die, but where to find one? The 40 tpi thread pitch was tough enough to find). I then cut the Coleman brass needle pricker rod to length and threaded it to a #1-72 tpi (which is what the Coleman factory threads were on this rod). The AGM valve was threaded to #1-40 (I think)…anyway, I chased/tapped/reformed the threads to the #1-72 (not ideal, but it doesn’t really need to hold much, just not fall out). With some judicious tightening, I got both ends of the generator to seal. I ended up replacing the leather fuel cap gasket with a Viton one I ordered off “the Bay”, the interior diameter was perfect, but the outside diameter was slightly shy, it still seats on the fuel neck rim just fine. I removed the superfluous washer from underneath the fuel cap screw (I now understand the design of the two piece style fuel caps…duh). After my repairs/refurbs/mods, I pumped it up and sunk it in my bathtub full of water to check for leaks A-OK. Oh, while I was at it, I sprayed it down with a stiff mixture of PineSol, Murphy’s Oil Soap and water and gave it a nice warm scrubby bath. I’m not planning on going any further on a refurb (re-paint/spit and polish)…..unless it looks like it’s going to rust where the paint is missing. It hasn’t changed in 50+ years, so I think it will be ok. Here are a few money shots. I used some older Coleman fuel (in case I had to dump it all out) so I think it could perform better with fresh fuel. It did settle down and clear up to a nice blue flame after a few minutes.
