    carb sync without air corrector thingies?

    Have a motion pro. The end of one of my hoses got ripped off in the move and I can't find the little air corrector that was in it. Would it be a waste of time to try and use it without any in? (pull the remaining 3) Motion pro sucks, yada yada yada, I've never had a problem with it.

    Which "Motion Pro"?

    They made three models that I know of.

    No, your engine sucks, the Motion Pro only tells you how hard.

      All the air restrictors do is dampen the vacuum pulses to stabilize the measuring devices be it gauges, liquid or rods. Just devise a way to do this by either sticking something else in the line or maybe even pinching it. As far as I know it has no bearing on the actual reading.

        That's what I thought, wasn't sure if they were mission critical.

          "Used to"???

          What does it have in there now?

          If you want, you can get blue fluid from Z1.
          It's not a very big bottle, but it's enough to fill a gauge from empty.

            Ya bought it off craigslist. Previous owner sucked some fluid down (probably why he sold it in retrospect) so I just refilled em with propelyne glycol
