I am a new member. My experience with stoves have been mostly with Colemans, Sveas, and Primus. Now i have come across an Enders, and am trying to understand how it works. I have read thru many threads and have been able to get my Enders stove going with a strong flame. Thanks for all the great pictures and valuable information. My new problem is that the flame dies slowly down to a simmer after about 3-5 minutes. Then i pump it up again and it burns great for a minute or so. Then the process repeats again. Any thoughts on where i can look for the cause?
