This is the part the mower blade attaches to, it is mounted to the deck of the mower by four bolts.
Spacer must be installed under the pulley.
Installing with the spacer on top of the pulley (or failing to use spacer) will result in damage to shaft and pulley.
The mounting holes on the Mandrel are not threaded. But the bolts that are used to secure the mandrel to the deck are self tapping. The Mandrel shaft goes thru the deck and the pulleys are attached to them, then the belt that drives the mandrels is placed in the pulleys.

A carburetor basically consists of an open pipe through which the air passes into the inlet manifold of the engine.
The pipe is in the form of a Venturi: it narrows in section and then widens again, causing the airflow to increase in speed in the narrowest part.
Below the Venturi is a butterfly valve called the throttle valve — a rotating disc that can be turned end-on to the airflow, so as to hardly restrict the flow at all, or can be rotated so that it (almost) completely blocks the flow of air.
This valve controls the flow of air through the carburetor throat and thus the quantity of air/fuel mixture the system will deliver, thereby regulating engine power and speed. The throttle is connected, usually through a cable or a mechanical linkage of rods and joints.
Fuel is introduced into the air stream through small holes at the narrowest part of the Venturi and at other places where pressure will be lowered when not running on full throttle.
