Abstract
A diaphragm carburetor for an internal combustion engine and method of assembly includes attaching an air-fuel mixing body to a fuel metering chamber assembly independent from assembling the fuel metering chamber assembly. The fuel metering chamber assembly has an upper body and a lower body attached to one another by at least one fastener with a diaphragm carried therebetween. A fuel metering chamber is defined on one side of the diaphragm and an atmospheric chamber is defined on another side of the diaphragm. Another fastener attaches the fuel metering chamber assembly to the air-fuel mixing body independently from the fastener attaching the upper and lower bodies together. Accordingly, the fuel metering chamber assembly is removable from the air-fuel mixing body without removing the fastener attaching the upper and lower bodies to one another preferably for cleaning of a fuel nozzle that when assembled projects into an air-fuel mixing passage in the mixing body.
