I need some help Ladies and Gents...
I have some carb issues. I'll try and describe it as briefly as possible but feed you all the relevant information.
Mikuni 38's with a carb rebuild kit and pods. Started leaking gas out of the pods. Turns out the floats weren't adjusted right. So I fiddled with those and now have them adjusted with a sight tube so the fuel is at the VERY bottom of the lip on the main body where the bowls mate into. Turn the fuel on and wait 10-20 minutes and no dripping. But there is a little ring of gas sitting inside the throat of the carb around the outside of the needle jet emulsion tube. Wait another 20 minutes and it eventually start dripping but VERY slowly.
Take the tubes out, O-Rings are kinda shot but not totally. Wrap some gas certified teflon tap in the seat under the o-ring as a test. Install and the little ring of gas still comes in. I try the same thing with some gas certified gasket sealant over the seat of the emulsion tube. Same thing happens. I break the carb down, clean out the teflon, gasket sealant and all and buy some 4mm by 1mm o-rings from McMaster and install after lubing up the o-rings with some motor oil.
NO DICE!!! I still have that ring of gas around the emulsion tube inside the carb body throat.
I adjust the floats until the fuel level is DRASTICALLY lower than all the manuals suggest and the fuel STILL shows up. The incredible thing is that even with the fuel level so low if I move the slide/needle I can see fuel inside the tube. So what it seems to be is that capillary action is allowing the fuel to climb the needle over the top lip of the tube to cause this puddle.
Any ideas or suggestions. I've been at this for nearly 2 weeks. I've attached some pictures. The two showing different fuel levels is just as a reference to where I'm setting the fuel height.
