    Think we have the same bracket, the horse shoe or 'C' piece has arms of .8"
    and a back of 1" and serves to space the actuating arm out to clear the air
    filter base. The 'L' part stands up 2 1/2" from the base of the C and
    extends towards the fender 2 1/2" from the back of the verical piece. The
    ball joint connector is facing in toward the carburetor on mine.

    I did the install on mine 17 years ago so forgive me. I'm a little fuzzy on
    the what I had to do to get full throw of the second venturi. I know I
    adjusted the control arms up on the foot well so that I got maximum throw.
    You might even go into the pedal stop on the floor board and adjust it all
    the way in though I don't remember messing with this. The forward end of
    the long arm that goes from the top of the foot well to the bell crank by
    the carb would not work with the stock spring clip. The angle was so
    extreme the clip fouled and wouldn't allow full extension. I took the clip
    off put the bent end in the bell crank and temporarily wired it on as best I
    could. It was supposed to be a temporary fix but is stll there after all
    these years and has never allowed the end to slip out. Don't remember any
    other mods that I did to get it to work. After grubbing every milimeter out
    of the linkage, the 2nd venturi just about completely opens. If 90 degrees
    is veritcal, it goes to about 87 degrees which I don't think limits the
    airflow much at all. Seems like I remember a couple hours of work for the
    installation. Suggest you keep fiddling and you should be able to get very
    close to maximum throttle opening.

    I've driven the carb with the jetting that came with. Think its a 135 main
    and 140 secondary jet. Seemed to work fine on a stock 7-1 engine. Never
    pulled the plugs to check the color but truck ran for around 14 years with
    out any valve or overheating problems and no valve recession from running
    unleaded. Mileage was decent at around 15-16 in an 88 with some long trips
    up a steep hill every day. I have never driven a series without the 32/26
    so can't comment on power addition. Know that going to a 2.5 cam, milling
    the head to 8-1 specs and a homemade port and polish job, still using the
    32/36, makes a BIG difference in the power.

    The breather on top of the valve cover is supposed ot have an 'O' ring at
    its base to seal it. The breather pipe goes to an 'L' fitting under the
    outboard front of the base of the aircleaner. The valve cover nuts have
    rubber washers that get very hard with age so may need to be changed. In
    any case there isn't much, if any, pressure in the valve cover though there
    is a constant supply of oil splashing around under the valve cover. You
    shouldn't see a lot of oil coming out. Leaks are generally around the base
    of the cover, and minor. If you think there is too much oil coming out of
    the valve cover area, suggest you put your finger over the end of the cap
    vent tube and rev up the engine. If you can feel much, if any, pressure you
    may have ring problems.

    Do a compression check and note the readings. Squirt a small amount of oil
    in the cylinders and do another compression test. If there is a rise in
    pressure from the original readings, your rings are going south.

    Hope this helps. The carb is sitting on my desk as I write and could take
    the portable phone out to the truck, if you wanted me talk you through it.
    My phone number is 808 325-7898 and its 6pm, here, as I write this.

    The 109 is up and running with a cable arrangement, by the way. I've
    noticed that all the parts are available to make the conversion through
    Pierce with the exception of an easily fabricated arm arrangement that goes
    on the foot well. Could take some measurements and tell you the pieces that
    you need to buy if you want to take the plunge.
