    Mickey Mouse Manometer

    Will followup when I use it to sync my carbs in the next couple of days.
    The dark cheese head screws are plugging the new vacuum ports.

    The way they make plastic bottles these days, they barely stand up on their own. An arrowhead brand bottle crushes just by putting an opened bottle in the fridge.

    My sole tip is to be sure that there isn't enough suction to suck up a big plug of water__you have a considerably larger reservoir than the average tube-type manometer! A hole in the sensing tube, something that can be partially blocked with your finger, would be one type of failsafe (I know you can take that little tidbit of info and run with it; no shortage of imagineering on your part ).

    I once did just that, it was even tinted with some Dwyer green dye; fortunately, the U-tube that I used doesn't have much capacity, but one good blip of the throttles, and it was gone!

    D'oh! - Too bad I didn't read the above first!

    They collapsed instantly and car ingested about a tablespoon of water. No harm done.

    Will rebuild with glass bottles and follow up.

    GregW - Ha ha - don't mind occasionally taking a wrong turn in my science projects.

    Have the new version built with Snapple bottles. Will fire it up probably tomorrow Monday afternoon.

    PS - one of the great things about the forum is to get this info out in public for others who want to spin off in their own directions.

    Didn't you see in the video that you're suppose to use Corona bottles?? I know from experience at Healey Week you SoCal guys have lots of empty ones around.

    Yeah the guy in the video implied there was a seemingly endless supply of them.

    OK - did the sync with the snapple bottles. Worked well, though have to say the crudeness of the linkage is the main problem with getting a good sync. No balance screw like the Webers or 240Z SUs. The 16oz snapple bottles are a little small. 750 or quart glass bottles would be better as they give you more water to work with.

    In my case, the rear carb seemed to have more draw, so I adjusted the fast-idle screw back and forth on the front carb to achieve balance.

    IMO it's better than the other methods because you don't have to remove the air cleaners.

    Do I see a new product coming, Steve? You got the 'stop' part, now you can add the 'go.'

    With the holiday season around the corner, Broguiere's eggnog will be hitting the shelves in select supermarkets. It comes in glass quarts and the best eggnog by far in my book.

    Final version: replaced the long tubes with these permanent M5 x .8 stubs. For a more permanent plug, replaced the rubber caps with 4-40 SS allen screws.
