Does Not Include 518709001 Throttle Lever.
Genuine Homelite replacement part, this item 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.

I installed this on my older Homelite Mightylite 26cc blower (UT08921). Used the old gasket since it looked good and didn’t come off with the old carb. Blower cranked right up on the first pull and runs like a champ. I was afraid the carb might need adjustments but it was dialed in. The only thing I did have to do was modify my original plastic throttle lever. The shaft on the original was flat on 2 sides while the new one is only flat on 1. I drilled out one of the two flat sides of the lever…
