According to,Bruce Palmer 111's book,How to restore your Harley-Davidson,An M54,was fitted to a Later 1951-52 45 W and Servi-car and an M54B was fitted to Later 1952-52 WLA.Hope this helps Steve.

The Linkerts sold as accesory carbs by Harley dealers normaly had 3 numbers after the letter and were sold as replacements for Indians and pre 1933 Schlieber carbs on Harleys.

I've been looking for my Linkert book which of course I can't find.
The M54 seems to have had the same part number as the M88.
The M88 = 15/16" venturi
The M54 = 1" venturi.
Was the M54 non vented aswell?

Yo Dave,M54 original H-D part no ...27122-37,M54B 1133-41M,M88...1133-41M.So yeah I guess your halfway right!Dead right on venturi size.Also the M54B had both fixed jets and high speed needles.Military fixtures.The M-88 main nozzles are internally vented,it also states that most other Linkerts are externally vented.
QUOTE"the M-54B is a modified M-54.The body's external vent hole is plugged with a brass plug (the M-88 and M-90 bodies were never drilled for vent holes)The main nozzle is internally vented by a slot cut into the 1" venturi. The M-54B main nozzle has a small hole at the venturi slot level,the nozzle must be turned so this hole is visible through the venturi's vent slot.It has a special forked spacer to help keep the main nozzle in position and a s
hort main nozzle spring.It uses the XA type float bowl gasket.
P.S. The books brill,but can be hard going!. Steve.
