Snowmobile engines are operated under a wide range of conditions, from idling with the throttle
valve remaining almost closed to the full load (the maximum output) with the throttle valve fully
opened. In order to meet the requirements for the proper mixture ratio under these varying
conditions, a low-speed fuel system (the pilot system) and a main fuel system (the main system)
are provided in Mikuni VM and TM type carburetors.
While this text covers the VM-type carb., the TM flat slide carb. functions the same. The circuits
function the same and tuning a TM would be done in the same manner as the VM.
