Having failed at the first hurdle - the Kerophile tea test - I retightened the NRV and then set the 1911 No.5 a far more challenging task... Brew a 6 cup batch of percolator coffee! A marathon run seems more like this old timer's thing. Around 15 minutes elapsed before I had my first glimpse of liquor in the sight glass. It is after all a marathon, and not a sprint! A couple of minutes later saw some hard boiling, with water and coffee grounds spurting out of the spout threatening to extinguish this old runner's torch! Bled off some tank pressure to produce a nice gentle percolation. Set the timer for 10 minutes to give a good brew. With five minutes to go I start to see fuel dripping from the pump rod collar! (Again!) We push on through the pain barrier... Two minutes left and yellow tongues of flame appear around the burner! The jet's blocking! After nearly 30 minutes of burning for a recently reserected stove it would have to be on the cards! We're so close to the finish line! I fumble around for a jet picker...one minute left on the timer and...the flame goes out. The coffee was done by that time so I'm calling it a win! Steve
@Funfundfunfzig Full score for persistence!!! This universal law applying to fettles (which I believed only applied to me): If everything seems to be going well, you have obviously overlooked something. Just my way of saying "Been there, done that"
I think having some experience with old stoves only means you know what has gone wrong. More experience might mean understanding what is going wrong whilst it's happening. True stove wisdom would allow you to predict a problem before it happens. But then what would be left to fix!?
Half the fun is the running around like yer arse is on fire, trying to think what's going wrong, and then saving the day. It gives on a sense of achievement to conquer a crisis. If it were all straightforward, it would be soooooo mind-numbingly boring!!! Mr Murphy's Laws have a valuable place in our world.
@Funfundfunfzig Your almost there . A little more tinkering and she'll be a real beauty and a joy to use .
I'm still don't understand how to service an NRV? I can't see any spark plugs, an oil filter or any way to crack it open??? What am l missing here?
Hi @Funfundfunfzig, Internal NRVs explained: https://classiccampstoves.com/threads/non-return-valves.6860/#post-64230 https://classiccampstoves.com/threads/pump-tube-nrv-assembly.14028/#post-138233 https://classiccampstoves.com/threads/georges-new-nrv-tools.17401/#post-177411 Best Regards, Kerophile.
@flivver I figure it's like Grandpa's 100 year old axe! You know! The one that's only had four new handles and three new heads!
