Genuine OEM replacement part, this part is sold individually.
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.

8) DO NOT over tighten screws as they are going into plastic.When resistance is felt on screws,
STOP. When both screws are even give an additional 1/8 turn. DO NOT OVER TIGHTEN.
9) With job is done it'll run like new. Only thing I had to do was adjust idle, very simple.
Just take your time and you'll be fine. Good Luck
Engine was hard to start but would idle once it did. Then it would bog down and die anytime you gave it throttle.

Wish the carb would have included the gasket though. Mine was fine to re-use but it would have been nice to replace it. The gasket is included in a gasket kit, and I didn't need all of the items on the kit. No big deal since mine was fine though.
