    I took the carb apart. It had 66 primary jets and 76 secondary jets. I left the 66's and changed the secondary to 72's. It had a 30 primary accelerator pump, and a 50 secondary pump. I put a 30 in the primary and a 30 in the secondary. If I can I'll be up and running tomorrow.

    Now just remember that it's always going to be richer than a vacuum sec 600 because of the extra accellerator pump. Everytime you plant your foot into it(to where the secondaries open), that extra pump comes into play. If you want, you can also disconnect the secondaries (by removing the linkage between the two)and fine tune the primary side for partial throttle cruising.

    Don't want to disconect the secondary. I'm only interested in performance, not gas mileage. I drove 626 miles round trip to Carlisle and I couldn't tell you my gas mileage. Again thanks for everyones imput.
