    Just as I suspected...going to soak the bowls overnight and try again tomorrow. Thanks for the link, back to the "grindstone".

    I pulled a wire off of my wire brush and worked it into the hole until I got all the crud out.

    High-E guitar string also works well. Carb cleaner from a can should shoot through the passage and several feet into the air when cleaned properly. PLEASE WEAR SAFETY GOGGLES WHEN PERFORMING THIS TEST!!!

    That maybe the key, I've been using a bit of safety wire and have gotten quite a bit of gunk out of the bowl side (Been clear) but the safety wire is soft and may not be getting thru the well side hole.

    You need to be careful you don't enlarge that hole. Try compressed air before digging in there.

    I believe Chacal sells a drill bit the correct size to clean it out.

    You could try a safety pin.

    Well I've soaked them overnight in the Gunk paint-bucket-o-Carb-cleaner which I set on top of the landlady's air conditioner to provide agitation. I find brake parts cleaner to be an excellent rinse to remove the carb cleaner residue. Now I'm off to Offline Skip's (the Shovelhead Advocate) to borrow a pin vise and micro drillbits. I will not be beat-down by a few pieces of potmetal.

    There's a video somewhere of how you want it to SHOOT OUT floating around here somewhere. Seriously... you know you're done cleaning it when the cleaner shoots out of the bowl better than the can. Take that red straw thingy and sand the tip of it down so it fits nicely into the hole inside the bowl. Blast away making sure its pointed away from you (and the bke, the car, + anything you dont want carb cleaner on. Wear safety glasses too!

    Success is at hand. Thanks for all the responses. The wire brush (my granddad's) bristle was the key. Only one of the holes cleared with the sanded spray tube method by itself. I bent the bristle 90 degree so it looked like an allen wrench and two more were easy as finding the hole and pushing the dirt out then spraying (First spray blast going from the well into the bowl). The cleanest looking bowl took the most effort and I had to press and twist the bristle to get it cleaned. From my initial probing from the bowl side, there was either a burr from manufacturing or a chunk of something in the port.
    Thanks again.
