Linkert MR-4 A

[T. Cotten]

Now that's different, Craig!

Although Type A DLX Scheblers were tapped like that to retain the nozzle, which may explain the missing spring.
(Please measure the threads.)

The nozzle shouldn't be as hard to remove as some..., (Like GX Scheblers).
If a cable doesn't work, then I resort to various pullers I have made.

The closest thing I can relate any of this to is the M-53 series, and I not only have very little experience with those, the 'drool pit' to the bowl headspace baffles me entirely.

The experimental blueprint spec's a -54 fixed jet; Is that a #9?
(I have no K literature.)
Whacking the nozzle spigot is another mystery.

The lack of lift lever and metering air jet to the LS needle bore on Craig's confirms that sort of lineage.
How ironic that they went from a restrictive bombsight to wide open with an integral "airhorn" .
They had to be intended for two very different duties.

The threads are 3/8x24.

There is a plug that goes in there Craig, and it acts as a nozzle retainer/seal. I'll try to get a pic of one for you.

The Schebs were larger, Craig,..

But their design may be a clue.
Note how the 'tit' that presses up against the nozzle is slotted to allow fuel and air to enter.

Viewing down the bore, is the nozzle spigot about an eighth inch below the centerline, or more like a quarter?

When the nozzle does come out, please observe for a gasket at the top shoulder.
And whether the nozzle bore is continuous to the body bore, or the nozzle is retained by the casting instead of the venturi.

Looking forward to it,

A hot air gun,heat the carb up a bit usually helps.Doesn't take much heat...no torch!Same with the little plugs.

I always torch out frozen plugs, Duffey!

But its a special torch.

Cotton,If I said use a torch I could see a potential problem with some of the group!

I'll try to remove the nozzle this afternoon.
Robbie; A pic would be great and thanks for the info.
Cotten; Thanks for your pics and info. I'll have to look through my junk and misc. boxes and see if I have a plug like that.
Duffey; Thanks for your help.

Well, after about 3 1/2 hours and a lot of *#@^!#^! language. It's time to leave it alone until tomorrow. I've tried Mapp Gas, and a cable ( the soldered end came off the cable ). I got it to move even with the throat of the carb., but that is as far as I can get it now. The bore that the nozzle tube comes up through is about the the same I.D. as the O.D. of the nozzle tube. Unlike regular Linkerts. I looked to see if I had a junk nozzle that I could cut the top off of and use it as a guide to pull it out with. I'll have to check my carb. collection to see if one of those have a junk nozzle that I can use.
