Our tub is slow draining and I'd like to snake it by going through the overflow but the small allen screws that hold the plate on seem to be stripped. This the plate: [IMG]https://kohler.scene7.com/is/image/PAWEB/Category_Template?$PDPcon$&$gradient_src=PAWEB%2Forganic-gradient&$shadow_src=PAWEB%2FBlank&$Badge1_src=PAWEB%2FBlank&$Badge4_src=PAWEB%2FBlank&$Badge3_src=PAWEB%2FBlank&$Badge2_src=PAWEB%2FBlank&$product_src=is{PAWEB%2Fzaa78350_rgb}[/IMG] The holes are underneath the plate, very hard to reach and there is not much clearance between plate and wall. I tried putting a pushing an allen wrench up there with a rubber band on the end but that didn't work. Any ideas on how I can get this plate off? Or can I snake the drain some other way? Thanks.

The toilet on the top floor of the house is often prevented from flushing partly, or wholly, by air bubbles that rise from the drain in the bottom of the bowl pretty instantly upon being flushed. I've read this can stem from blocked jet holes, but cleaning them with a small nail and then pipe cleaners, all around the inner rim of bowl, has not stopped the vigorous bubbles from coming up the drain hole, or solved the problem. (I also have cleaned the large jet passage at the bottom.) Sometimes the bubble is more like one large bubble, and sometimes, many small ones. Sometimes, it just flushes like a champ for no apparent reason. Any thoughts on what might be causing this problem or what I could do to try to narrow it down?
