So I recently acquired damaged decal but unfired 222B as a birthday present (thanks to my girlfriend) and I’ll tell you it’s been quite an ordeal getting her running!
The valve was incredibly stiff (once the lantern got hot, turning it off felt like I was gonna break a finger), but after much fussing, I figured out the valve stem was way too wide in diameter, some time in my drill and some 2000 grit sandpaper solved that problem.
But now onto the fuel issue (And just to cover some inevitable questions, shut off o-ring tested for full functionality and pressure holding, zero leaks, valve o-ring was replaced, CF is only fuel used)
Everyone is always talking about how great the 222 “smaller” generators are for their much smaller orifice in the tip for fuel efficiency and longer run times between pumping, but I’ll tell you, at least with the genny that came with this thing? It sucks and I hate it.
Despite the thing never even having had fuel in it before I first tried to start it up, the generator clogged up twice and had to be disassembled and cleaned and even when it finally did run okay, it acted incredibly lean. At first I thought it might have been a lack of air issue, but as soon as I partially covered the air tube, it got much brighter, the burn stabilized, the turbulent, garbled sound from the burner subsided and it just seemed much more happy.
But I wasn’t going to hold my finger partially covering the air tube every time I knew I had to figure out the issue.
- I checked for valve obstructions, there were none.
- I checked for adequate fuel delivery, with the tip off of the generator fuel shot out in a powerful stream, so no issue with the F/A tube.
- Even though all indications pointed to a lean condition, I still checked for obstructions in the burner frame. Ran wire and pipe cleaners through the whole passage. Clean as a whistle.
- I even double and triple checked the burner cap and screen and scrubbed them clean.
Finally I came to the conclusion that the orifice of the generator was just too small. Knowing that the 226 generators have larger orifices and are infinitely easier to find (can still be found on Amazon), I bought one and awaited eagerly for its arrival.
Once I got it, I quickly realized it was far too thick to be installed without modifying the heat shield and the proportions of the tip that enters the burner frame were different. But I still wanted that orifice on my old generator. So also wanting to swap over the new pricker, I got to work with my dremel dissecting the 226 generator that coleman had completely crimped together to prevent disassembly.
- Swapped the tip over to my old generator (easiest part)
- cut around new generator at the base to remove the crimped brass retainer and pricker rod
- cut the brass retainer so it could be slid over the stamped widened section of the pricker rod
- filed down just enough of the stamped flattened section of the new pricker rod so it wouldn’t interfere with movement within the old spring and fiberboard tube design of the old generator internals
Then I carefully reassembled the new parts into my old generator, reinstalled the generator gave it a test run to confirm it was squirting fuel, reinstalled the burner frame, tied on a peerless 2C-HG and burned it in with fuel on. Shrank down to a good, small size and now this lantern screams steady and pumps out the light. Maybe I have to pump it up around every 45 minutes to 1 hour, but that sure beats an anemic, pulsing mess.
I hear so many people praise the early generators, but my experience has only made me wonder if this kind of poor performance is one of the many reasons they switched to the fatter generators with larger tip orifices (RUG compatibility being the other). Anyone else have a similar experience?
