I had the same issue. Total disassembly was needed to access the Venturi. Soap
had hardened inside it. When cleaning out the brass fitting leading to it
there was a small bearing with a spring behind. Be careful not to lose as I
almost did. The hardened soap was difficult to get out, but using a paper clip
should work. I also blew out the blockage with a can of air duster. I just
hope that I put the bearing and spring back into the fitting in the correct
order.
