Hi guys, I got my Enders 9061 working last night having soaked the leather washer overnight. While it does work, the pump only pressurises the tank on the last inch of travel. I used standard rubber O rings as a test while I wait for my seal kit to arrive courtesy of RussianJesus - thanks in advance. I got a nice blue flame, no yellow, but the spread of the flame is uneven. It usually starts off OK, but after about a minute some of the holes aren't lit. Is this a positioning problem with the inner cap or something else? Secondly, the pump tube had suffered at someone's hands before I got it and it wasn't 100% round! I worked on it VERY carefully indeed and it's a little better, but what would be the best way to re-rounding the tube? Will a new pump washer be able to cope with a slightly irregular tube? I remember reading a thread on here about just this point but I can't locate it again. All that aside, the Enders 9061 is an awesome stove (albeit way over-engineered!) and instantly became my favourite!
