    There's gotta be a better method of adjusting the carburetors on a '76 308 than that described in the 308 Workshop Manual:

    1. Tighten screws C (idle mixture) then unscrew them for 3 turns.

    2. Reach 900-950 rpm by operating on screws A (throttle).

    3. Using the motometer (I have the SK type) adjust first the two carburetors of the left head (front) then adjust of the right head (rear) by operating on screws B.

    4. Eliminate small differences between the two casings of each carburetor by operating on screws D.

    Then it goes on to say balance the two carburetor lines by operating on screws A and to meter the mixture, operate screws C for 1/4 turn each time until the "required condition" is achieved.

    This is confusing and seems full of errors. It does not describe what the "required condition" is.

    And I assume the left head (front) describes cylinders 5-8, and the right head (rear) describes cylinders 1-4.

    Geez, there's gotta be something somewhere better than this for adjusting these carbs.
