My 020avp's carb says WA-1A on it. I rebuilt it with new gaskets and diaphragms the other day. I don't remember taking off a circuit diaphragm and I saved everything I removed (I thought). Anyway the kit came with one and it seems that it would only block the high speed circuit. Does anyone know if this carb used a diaphragm or was it a circuit gasket only?
