Thats definetly fat way to rich. I would do what Cab said first and jet down the primary's some first. And go at least 3 sizes as you want to see how much a difference does. Once you get it lean enough you can tune from there. Check the power valve while you are there because if the diaphram is blown it will pull that fuel right thru the vacum source that goes to the power valve. Clean the plugs or replace them and then jet down and drive it. Thats keeps it simple for now and lets see the results from that. You cruise on the primary's most of the time so I would not worry about the secondaries just yet. Ron
