    UPDATE: The truck currently starts & runs good, idle speed a little high by 100 RPM or so (but not always?) ~ got my laptop fixed & can upload photos now ~ used laser tach, timing light & hand vacuum pump to discover a new problem, the distributor vacuum advance diaphragm began leaking, did not advance the ignition timing ~ tested the mechanical advance, it works ok...

    1) Replaced the dist vacuum advance actuator & tested vacuum advance, works good...
    2) Changed engine oil twice & added polymer-ester additive to prolong life of flat tappets ~ no more noisy tappets

    NOTE: Telltale sign of a vacuum leak on my truck is the brake pedal ~ the power feel of power brakes is deminished enuff to feel in the foot...

    REBUILT MIKUNI PHOTOS


    NOTICE ANYTHING MISSING ON THIS CARBURETOR PHOTO (?) LUCKILY FIXED IT BEFORE CONNECTING FUEL & COOLANT :^) COULD NOT GET THE AIR CLEANER TO FIT ON THE CARB & WHEN I WENT TO GET THE MISSING PLATE & GASKET, NOTICED I ALSO FORGOT TO INSTALL BOTH THROTTLE VENTURIES OMG..!

    Me too, a reference was made to 'ALL' carburators using brass plugs for the 'rifle drilled' passages.
    The statement is in error!!!
    Oh, xbox,
    My '88 with the P.O.S. Jap/French bastardized compromise engine control system ---
    1) was supposed to be 'lean burn' (jet valve)
    2) was supposed to be 'altitude compensating' -brain dead T/P & O/2 interpolation maps
    3)was supposed to provide > 29 MPG , < 2.9K RPM

    claych ~ yeah, I know what you mean..! I thought the 1986 carb'd trucks were the ultimate pain until I saw diagrams of the 87 'n later Gen2 carbs & engine bay of vacuum hoses -- I bet assembly line workers enjoyed slapping all that stuff together..! LOL 29MPG hmmm..?
