LMS Carburetor

Horizontal Models 110000, 120000, 150000

The exact type of LMS carburetor can be identified by a number stamped on the edge of the mounting flange (A, Figure 25). These carburetors have a fixed high speed main jet, a non-adjustable idle mixture (except on early production models), and manual/remote choke. Snow engine carburetors utilize both a primer and a choke for improved starting in cold temperatures.
