    The WUR sets the mixture rich when the engine is cold. It does what a choke does on a carburetor.
    If not familiar with fuel system components,
    The WUR/CPR is bolted to the LH rocker cover. You remove the larger fuel line banjo bolt. The screen is at the bottom of that port.

    If you break the connection you should replace the copper sealing washers.

    Do you guys have a part number for the copper sealing washer? Will that be the same copper washers that are on the rest of the banjo bolts going into the fuel distributer?

    Never re-use banjo bolts? Or washers? What?

    CO adjustment hole?

    So is this the CO adjustment hole? I have heard people saying this hole should have been plugged? Mine was definitely not plugged up. I also can't seem to find an Allen wrench that fits to turn anything inside that hole. I can barely look in the hole but don't see any female Allen head at all..... What sort of tool do I need.

    you need a long 3mm t handle allen wrench. Sears has them. You absolutely need that plugged. A bolt or golf tee works. DMC also has a little plug with a wire loop on it. Without it plugged, you have a vacuum leak.

    That's what I thought. I just noticed it and was playing around with plugging it with my finger, but didn't notice a difference in idle at all. Weird..... Do you happen to have the DMC part number for the plug?

    I think I found the reason no tool would fit...... Is this the plug everyone is talking about drilling out? It looks like the PO attempted, but gave up prior to tapping though. I suppose that would also explain why I didn't have a vacuum leak with the upper hole unplugged. Either that, or the PO iwas an idiot and tried to drill out an Allen hole? Guesses?

    Your plug was drilled out in your first photo. This photo looks like the PO drilled to deep into the 3 mm "Allen" head bolt.
