Abstract
A simple start diaphragm carburetor includes a carburetor body, a main adjutage, a throttle subassembly, a choke spindle, a linkage subassembly and a start fuel passage. The linkage subassembly includes a first linkage subassembly, a reset element and a second linkage subassembly which cooperates with the first eccentric element to form a linkage. When the first linkage subassembly opens the start fuel passage, the second linkage subassembly drives the main fuel supply channel to be open partially. Rotate the throttle subassembly and the choke spindle is reset by the reset element, thereby closing the start fuel passage. The simple start diaphragm carburetor can increase the probability of the successful start of an engine and keep the engine warmed-up for a long time, and reduce the burden of the user.
