Linkert main nozzle varaiations

[tfburke3]

I have a M6 Linkert that has 4 small holes in the main nozzle ,different than say a m344 that has 5 holes ,three small and two bigger at the bottom.
The m6 first hole is inline with second hole from the top of the m344.
Looking at nozzle size carts its suprising too me how much variation there is for motors of the same displacement and design.
Was linkert fine tuning the nozzle design as years passed?
I think I am going to put a m344 nozzle in the m6, stock 34 chief with 47 std. cams and lifters and alum pistons.
What should I expect?

Great question, I would like to know the answer to this myself. Hopefully Cotton will see this, he seems to be the "go to" guy when it come to Linkerts. He probably can get you an answer.

I'm only a student of these things, Folks!

Since nozzles are easily replaced, they were often switched or altered.
The design is wonderfully forgiving.

Tom's sounds like a common HD flatty model nozzle (quite close to the Indian M741 series.)
Assuming it is a "Beck" M6, then the standard Indian nozzle should be proper, with a 1 1/16" venturi, vented, if the body is not.
All other things must be in order, of course.

(That doesn't mean a Bonne nozzle with a 1 1/8" venturi wouldn't please, especially on modern highways....)

Thanks Tom.The M6(no Indian) body vented,doesn't say Beck but I'v read they were the retailer.
I will try the M344 nozzle.
BTW speaking of 1/1/8"the 80" motors list 3 different nozzles m350(2) and another for m352 ,with main bores #28 or #36 and metering hole size variations for exactly the same motor.Seems odd for a carb with adjustable hi and low speed neeedles.
Thanks again,
Tom

Tom!

I wouldn't call it a "BECK" without the "INDIAN" stamp.
If yours has a two-screw intake, then it is earlier, I believe; Application unknown.

The mysteries and enigmas surrounding these devices are endless.

Tom,I have only read as sold by Beck when trying to find info on this M6 (no indian stamp) 1 1/4 model M Langsenkamp-Linkert 3 hole manifold ,2 hole air cover ,with traces of original nickel plate,and one of your handcrafted floats.
