I'm rebuilding a Zama C2S carb. I pulled the bottom metering plate off and the diaphragm and plastic piece just fell out. The metering diaphragm does not have the circular metal piece like most. This one uses a plastic piece (#15) that just sits on it...(I think).
My question is... does #15 just sit on the lever (#1)? It seems it would float around and come off the lever. I wish they woulda use a normal metering diaphragm.... I hate Zamas.
