CARBURETION

Typical Mikuni Starter System - Closed Throttle
Mikuni carburetors use a starter enricher system rather than a choke. In this type of carburetor, fuel and air for
starting the engine are metered with entirely independent jets. The fuel metered in the starter jet is mixed with
air and is broken into tiny particles in the emulsion tube. The mixture then flows into the plunger area, mixes again
with air coming from the air intake port for starting and is delivered to the engine through the fuel discharge nozzle
in the optimum air/fuel ratio. The starter is opened and closed by means of the starter plunger. The starter type
carburetor is constructed to utilize the negative pressure of the inlet pipe, so it is important that the throttle valve
is closed when starting the engine.
