I cleaned up a Yamaha 9.9 hp carb. The idle jet was full of crud. Reassembled it and installed. Now it runs super rich and won't get up to normal RPM. I think I must have reversed these two lines that control the BVSV that takes the place of a choke. One of these inlets has a large hole and the other a very tiny hole. The left one has an A over it the right has a C. I did not mark as I should have. I was hanging off the back of a boat in the water. I know you're saying just reverse and try. But it carboned up and fouled the plugs really quick. It's like running with the choke on 100%. Clymers doesn't show much. Any idea on what goes where?
