41CDZ11G799 MTD Trimmer - Overview

This fuel tank assembly is supplied by the original manufacturer for use in trimmers. It is responsible for storing and transferring fuel to the engine for combustion. The assembly consists of a plastic tank, a fuel cap, a fuel filter, and the fuel lines which have a diameter of 0.25 inches. If the fuel tank is damaged, or the fuel lines ...Read moreare clogged, the assembly will need to be replaced. A faulty fuel tank assembly will result in fuel leakage, hard starting, rough idling, and poor equipment performance. To begin, drain the fuel from the tank. Disconnect the fuel lines and remove the mounting hardware that secures the assembly to the equipment. Pull off the old assembly and align the new one with the mounting holes. Secure the assembly in place and reconnect the fuel lines. Refill the fuel tank to complete the repair.

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 rotati...Read moreng 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.
