Jet adaptor in the Leader

Hello all
Yesterday, for the first time, I couldn´t light up my Accucraft Leader. After many attempts, I decided to clean the jet nozzle. I so did, and that might have solved the problem. But I was really surprised when finding out that the adaptor, holding the nozzle, is just pushed in place in the burner with no screw securing it. I noticed that it could move about 1mm. And there is a gap against the collar in the back end of it. Thinking that this is a possible source for "false" air to obscure the burning, I wrapped some Pfte tape around it before pressing it back in it´s place. The loco became easier than ever to light, and it got a slightly different sound from the burner. In short, I belive it now works better and even has got a longer running time
And now for the question: The adaptor is still just pushed in place (but now with Pfte tape around it) and after some use, I´m afraid that it will be leaky again.. Have anyone a solution on this? Or am I wrong, maybe it´s not a problem at all?
Regards to all from Michael

After having streaming issues with my Ragleth I reseated both the jet and holder with PTFE tape and have found it steams better and runs a lot longer with a cooler smokebox. I don't know how long it will last tho!

I think I shy away from accucraft for this reason. Can the gas burner and filler be ripped out and replaced with the roundhouse counter part? I think this would solve all issues surely??

Someone in my local area has a Caradoc with a roundhouse burner installed, however it is just a noisy (if not louder than mine is now), doesn't appear much easier to light and IMHO doesn't last as long!!

I am very fond of my Accucr. Leader

Before I bought it I was warned that the loco would cause me lot of trouble

(made in china and so on..) But I haven´t rejected for one second that I bought it. The burning problems is something I can cope with, in fact I find it very satisfying managing to solve small problems and get the loco back in working order. And this I have done with all makes I posess, Regner, RH, and the Leader from Accucraft.
So, what I´m trying to say is, that this problem is not big enough to avoid Accucraft locos

I really hope the different makes will live on and give us many choises when we shall choose motive power...

I know the holder is a push fit but, maybe the copper pipe needs a slight bend to give it a bit of tension. Haven't noticed that problem with mine. One of my other Accys kept getting a blocked jet, maybe some particles in that cheap gas I've been using.
Someone did suggest a filter behind the jet but what would you use?
I did notice a filter in my Pearse loco

Over on the 16mm NGM association Facebook page a photo was posted of a piece of coffee filter paper which had been mounted behind a jet as a filter for 10 years. Proved its worth as it was a very brown stained colour.
Alternative is a piece of unused teabag material.
Apparently fag filters are no good.
The jet is also a loose fit on my Accucraft Edrig. I guess drilling a small hole, tapping it with the appropriate thread and fitting a small securing screw/bolt like most other manufacturer's do is a solution.

How is that Pearse loco set up on the gas? is it similar to the Accucraft jet?

Yes it is very similar and does have a set screw to hold the jet housing in place.

Ah I see. Perhaps a small drill and tap would work well?
I have always liked the accucraft excelsior. Wonder if you fit the Milton locomotive works burner, acme gas jet and a larger gas tank from roundhouse (fit dependant) if you could get a longer run out of them?
I suppose my only issue is I quote like a quiet burner....

With Leader and I don't know if Excelsior is the same, the water will run out before the gas, hence the water level gauge. It is a more hands on engine so if you've stopped for water, why not gas up while pressure is raising so no need for a larger gas tank.
That's saved you a few quid to buy the Milton burner.
Wrapping Accucraft burners in stainless steel mesh does make a difference too.

Hi all
I´m wondering if anybody knows of any photos of this?

I am very interested, but I need to see some pictures before I dare trying it out on my own loco

Thank You. Rebelego

That´s exactly what I needed. And now for the 1000kr question: Do yo know what it is called, and where I can find the right kind of mesh here in Norway

Something like this should be suitable with a mesh count of 40.

Or you could by a kitchen wire mesh sieve and cut that up.

Well, I have just used the mesh from a fry pan lid from Biltema:

But, the wires are too thin, so it doesn't last very long. I recommend to find something else.

I bought one of the frying pan splash covers and then tried some stainless mesh from ebay. I will have to dig it out and see if I can identify it.
I know one mesh I tried really made a difference in a bad way. It might have been too fine and changed acoustics of the tube?
Anyway I couldn't understand why the burner at a high setting started to whistle, horrible. Took it off and it was fine and a courser mesh was ok too.
If cut and wrapped round something smaller than the poker it will stay in place or use some of the mesh strands as a wire to bind.
Bit late in replying but had a good excuse, been away in York to see the A4's lined up

Thank you all for all advices
I have now ordered mesh with a count of 40 as Superbiker suggested. I think I´ll go for the teabag thing behind the jet also. Is it just one layer, or is it ment to be folded so it gets thicker?

The piece of used filter paper that was shown over on the 16mm Facebook page was folded up, so I guess you fold a piece up to fill in the space behind your gas jet in the holder.
