O.S. Carburetor Body #40E (large view)
Notes from our tech department:
This is the Carburetor Body for the #40E Carburetor.
This is used on the O.S. Max .50SX-H and HG Engines.


Aluminum construction


One Carburetor Body


Outer Diameter of Carb Base: 11.4mm
Height: 38mm
Width: 37mm


This is the Carb Body ONLY. It does not include the rotor, throttle
lever, needle valves, mounting screws, and so on.

There is only one O-ring for the carb body. The O-ring for this is
different than the one for the .46-FZ. The proper part number is
OSMG6228, as this O-ring is slightly larger in diameter and a
little thinner.
The best way to insert the carb assembly is to place the brass insert
about half way into the case, put the O-ring around the brass
insert and press the careb down tight against the case. There will
be a gap between the base of the carb, and the case, but the gap
will be very small. You should only be able to see the black O-ring
