Flame at Needle ???
-
Hey Michael!
Welcome here! => The flame you see at the needle (# 68 ) is normal (if the light gets turned off)
The needle has just the function to keep the nozzle (# 50) clean of rests of (burned) fuel or dust.
If the latern is turned off, part 193 stopps the fuel going into the carburetter (# 152 + 153). But the fuel-rests which are in the carburetter will still be burned.Many greetings!

Hi Michael,
like Ben mentioned, when you shut the lantern off by handwheel, there can appear a little flame at the jet for some seconds.
But not in use, if you have a flame there in use, the jet loosened and has to be fixed.
Best regards, Björn

Ben your english is perfect..if not better than mine :)..and your answer even better. Thanks for the info Bjorn, the needle has come loose
Im having some teething problems with it. It seems to running a bit fuel rich, should i ajust the mixing shaft???
-
if the mantle glows in taints of yellow or orange than yes, place the mixingshaft 1-2 mm higher. 14-16mm between shaft and jet are perfect.
It should glow bright white or with a light greenish touch (what would be perfect for a Petromax on the green Island)Good luck, Björn
-
Yes pleanty of yellow and orange and FLAMES!!! I will ajust and see how it behaves...And i shall return (With or without eyesbrows!) to tell.
Thanks Bjorn

A little hint, shut down the lamp before adjusting and let it cool down
It helps keeping eyebrows and prevents durable fingerprints on your lamphood.
Good luck, Björn
-
Yes indeed
Lamp is running much better now thanks all..Great looking lamp..its a pity to get that nice chrome hood all discoloured from heat...Would be nice have have a second one to keep in show condition or maybe a brass one next!! -
oh, experts like these colours and proof of use.
it shows that the lamp worked well and wasn´t a useless object. -
hehe, be careful.
First you want one, than two or three - just for use... and then it ends up like this:
You possess a little museum and everybody says that you're insane
Good luck, Björn
p.s. the brass-hoods getting silver on top in use
-
again does one want to become addicted? petrolitis the virus is incurable:D
-
Borjn..WOW!!
What a collection!..Well done you..Im developing a thing for lamps...My Mrs knows that im a little insane already so i have a head start -
Ruler of light
I think its too late!!
..Ive got the bug -
would appreciate any further info on tryin to get this lamp to stop throwing flames...It could be my first and last Pertomax
-
What’s the matter now? Any further flames at the needle?
-
No more flame at needle:)...It has just turned into a flame thrower..Big ones
Had this problem with a petrol North star but i thought it would not be an issue with a paraifin lamp -
Did you pre-heat your Petromax correctly for 80 to 90s? Do you use the Rapid?
See if your inner mantle (# 117) has been accidentally moved (the jet needs to point into the mixing shaft). And while you’re at it see if the jet has loosened.
-
Hi Michael,
flames do always incicate something as loosened - or too short preheating.
It could describe a lack of pressure also, then sometimes the flame from inside the mantle jumps back into the mixing-shaft or to the needle - this is dangerous (backdraft) and can glow away your mixing-shaft.
This appears with a strange noise like a bumblebee in the upper lamp.But i would guess your problem appears because of the first two mentioned problems.
Good luck, Björn

Thanks all
I will put my engineering skills to the test
and report back on this gripping issue:D
