Would silicone fish tank air line work for a Monometer?

    I think it will too, I'll just have to plug the inlet on the side of the gate valve with epoxy or aquarium sealant or something. Then it will be a 4 way tee as long as all of the shutoffs are turned on.

    There you go graig50, you can get the stuff REALLY cheap, LOL!

    I was thinking about getting the supplies, then mounting them to a yardstick in line with eachother so it is a nice solid accurate setup.

    Don't forget to make some RESTRICTORS.

    While I can understand the enthusiasm and the your energy to create a some elaborate set-up.

    The "Ages-old, tried and true, product of evolution" ... and, found in the toolbox of nearly every single wrencher -- turned -- tuner, who deals with multi-carb vacuum hook-up's is:

    Rick - what do you mean by "restrictors?" Where would they fit in the plans?

    Update:

    It DOES work! It is very sensitive tho, and it will suck the fluid down enough to get air in the lines if your carbs are too far out of whack.

    Home depot has some heavy duty clear hose for about 7 bucks for 20 feet.

    When I adjusted mine I did so with the thumb on the starter button and a finger on the kill switch. Soon as I saw the fluid getting ready to go over the top of the loop, I'd kill it and adjust it until I could start it and stay in the tube.

    I made a two line manometer out of 20 feet of hose. I lead about 5 feet for the carbs, and attached the board (a cheap aluminum yard stick) and left the rest dangling for the "bottle".

    I filled it with some 2 stoke oil. you can also get that at Lowes or Home Depot for about $1 for a tiny little one or two ounce bottle for weedwhackers and chain saws. It was esy to see and thick enough to not be "jumpy".

    the restrictor Rick is speaking of can be a simple vacuum fitting that is partially blocked off, installed inline from the carb vacuum port to the manometer...

    At low RPM, the vacuum pressure goes up and down very rapidly, making it almost impossible to get an accurate reading. The restrictor blocks some of the air flow, keeping that gauge from dancing like crazy.

    I also found that you can gently pinch the vacuum tubing, essentially producing the same effect. It's just a little awkward pinching the hoses and messing with the adjustment screws at the same time :) so an extra pair of hands could be useful.

    You take a Union ... used to join two lengths of hose together ... run a Carb Cleaner or a WD-40 "Red Tube" all the way through it ... Fill the Union with Epoxy and wait 5-minutes.

    Then, cut-off the Red Tube ... sticking-out of each end.

    Badda Bing ... Badda Boom. "Restrictor"

    Make 4 ... use 'em!

    They "Quiet-down" the wildly fluctuating pull of vacuum to a nice little little vibration.
