Why does the motorcycle have intermittent fuel supply issues?
1 Answers
Motorcycle fuel supply issues with intermittent operation are typically caused by a clogged carburetor. Below is relevant information about carburetors: Main classifications: Carburetors are divided into simple carburetors and complex carburetors. They can also be categorized as downdraft and sidedraft types. Based on throttle valve design, carburetors are further classified as rotary type and slide type. The rotary throttle valve features a disc-shaped valve that rotates on an axis between the carburetor throat and intake pipe, adjusting the airflow passage area. Basic structure: A simple carburetor consists of three parts - upper, middle, and lower sections. The upper section contains the air inlet and float chamber, the middle section houses the venturi, jet, and nozzle, while the lower section includes the throttle valve. The float chamber is a rectangular container storing fuel from the fuel pump, with a float that controls fuel intake based on fuel level height. The nozzle in the middle section connects the fuel inlet to the float chamber's jet on one end, with the outlet positioned at the venturi throat.
