    Anyone ever had this Happen? I have thoroughly cleaned the carb, have taken all apart even the emullsion tubes etc. Everything was new last month I put about 300 miles on them. I cant get 1 carb to pump fuel from the bowl to the squirters and dont understand why.I get plenty of fuel to the bowl and the needle and seat close like they should. Anyone been here thanks for any ideas etc

    I'm wondering if the rebuild kit was from Speedway, if so the accelerator pumps are garbage..They fall apart, that could be your problem

    Could be one or all of the following...

    * Crap pump, like Duane said.
    * Blocked powervalve (due to crap pump).
    * Plugged dicharge jets (also due to crap pump).
    * Crap pump.
     

  5. Swap the pump with one that you know works. See if that fixes the issue. If not move on to the power valve. After that I would say the tubes are blocked. Force air back thru the tubes in any way you can to clear them.

    There must be check valves or balls in the pump circuit. I'd bet one or both is stuck. If you manually push the plunger down and it feels stiff but no squirt, then something is plugged or stuck check valves.

    On most carbs, one valve opens to let gas get sucked into the pump well, while the other one shuts, so it can't suck air into the squirter.

    Steel ball missing or crap in the pump housing. The ball should be in the bottom of the pump housing with a wire ring placed to hold it in place.

    Has anybody seen this car. Last seen in NJ.

    Meantime, also scrutinize the check valve under the center screw plug between jets. It is another place crap from the crap pumps might have lodged, and having it blocked with crap would have put yet another bypassing leak into your crap pump circuit.
    Max has a nice tool for putting a mighty blast of air through the curved pump tubes, which usually in my experience produces a blast of dust out of supposed clean tubes...
    Mine is modified to run off of my traditional compressor, a one wifepower 1935 Ford tire pump...

    I would like to see a catalog of all of his available bits and toys...I suspect he has some goodies!
    The adaptor threads into the power valve hole and hooks up to air. Mine is fitted with a Scrader connection for a tire pump...

    Pictured is the discharge jet blowerouter tool and a couple of handhewn "spotfacing" tools w/pilots for dressing bowlplug and fuel inlet gasket surfaces. Not pictured are fixtures and anvils for staking chokeshaft and throttleshaft screws. Sorry, no catalog...

    I realy like the hand held spotfacing tools. I made a jig and use my small drill press. I also made a tool for the discharge tubs and use cutting torch tip cleaner, small and it cleans also..And , computer keyboard dust cleaner in a can for the tubs, carb cleaner in a can with noozle it fits over the tip of the tub..Just some other ideas for the clean the discharge tubs..
    Realy nice creative work Max..
