Hello!
Back in march I purphased a new MSR Dragonfly. I got to test the stove at home twice, before it cross threaded while trying to adjust the flame after doing a boiltest.
The flamecontrol feelt very gritty right out of the box. My hope was it would improve with some use, but I was wrong. I took the stove apart after it crosstreaded, upon inspection I noticed a copper-colored substance that reminded me of copper-grease. No clue why this was inside the stoves body.
I got to adjust it a couple of times before dissaster struck, the controller was gritty and when you adjusted the flame it would shoot fireworks, like there was debris losing from inside(the copper-like substance).
I got a new replacement after some time, and I was curiouse if this stove also had this copper-colored substance inside its body. And sure was I right, there were loads of it!
I started to clean the stove with the provided cleaning tool for the dragonfly(Flamespreader, jet, shakerneedle and spindle was removed). I did follow the cleaning procedure explained by MSR and flushed the stove several times with white gas. At the end I lost count of how many times I did this procedure… it was impossible to get rid of the copper-colored substance. Controller still feelt gritty, but I wanted to see if it could work. Put the stove back togheter, primed it, started it…it was shooting fireworks, still gritty, and started to block the jet a few times. Then I said to myself, Im going to return this stove and get a refund. While trying to adjust it you had the feeling the threads would cross-thread any minute. Upon inspection you could allready see defects in the threads.
This explain the gritty feel on the controller and why the stoves was shooting fireworks when you tried to adjust the flame. The substance inside the stoves are causing a major problem, no person would have a chance having a reliable stove.
I have no clue what MSR have been up with these two dragonflys, they were produced back in 05/22.
I noticed somthing on the boxes the stoves comes in from MSR(I own several stoves from them).
MSR XGK says “Made in the USA”
MSR Whisperlite International and MSR Dragonfly say “Assembled USA of U.S. And Imported materials”
Im not sure what exactly this means, but for me it seems like they are producing the parts for Whisperlite and Dragonfly somewhere els than Seattle. If they have outsourched the manufacturing of Dragonfly it could very much be the problem in this case.
I found one other guy at classic camp stoves that had the same experiance with his Dragonfly, this stove was also made in 05/22. Also found a case at reddit with exactly the same problem back in 2021, in the picture provided the copper-colored substance could be seen.
I have a fair bit of experiance with liquid fuel stoves, I have several of them in fully working condition from 1950s until todays models.
Anyone els had this type of experiance with Dragonfly? I still want a Dragonfly, but thinking of getting a second hand one, one that has a productiondate far far away from 2022.
The crosstreaded spindle after two uses.
Copper-colored substance/debris inside the new stoves. This is just some of it.
2nd spindle showing marks after two uses. No wonder the controll feels gritty. Allready some signs of crosstreading in the rear part of the spindle.
