Now how does that happen?

Just got around to installing the premium tuners kit along with a lot of wintertime bikish projects. They bike, my custom EVO Frankentrike with a 1998ish EVO. Custom air cleaner, pipes, and a mild cam has been running just fine for years but I figured a carb tune-up was due. Replaced the #45 pilot and #185 main with the new ones and then the rest of the new parts. A little fiddling and the bike startup up. Let it warm and tried to adjust the mixture. Nope no change in idle speed whether it was screwed in or out, virtually no change. I can adjust the idle speed up or down with the isle speed screw but the mixture adjustment does almost nothing. I just changed the pilot to a #42 and it's some better. The idle will slow a tad and stumble a tiny bit with the screw lightly seated. Run it out and you get a really fat spot where the bike seems to be running really well, but you can go almost all the way out and the bike still runs. So what is going on here? The fancy mixture screw doesn't do anything, in or out. Scratching my head.

Thanks for the help, I'll be looking closely at what you suggest since this does appear to be a too rich situation. I changed from the original #45 I had been running to a #42 which seemed to help the rich idle situation some. I'll try the #180 too. I'm also wondering if the needle might have anything to do with this? I used the needle and spring included in the kit and am wondering if the spring might be too light?

I think I may be tracking down the problem. I spent all day cleaning and testing all the passages and I am pretty certain everything is clean but there was no change - the EZ Just mixture screw still does little to nothing. I removed the air cleaner while the bike was running wondering if I could see anything. Fuel is spraying up around the slide needle from the needle jet. Now I need to know why because that would surely make it run rich.

Things are a little better, not perfect but better. I put the old emulsion tube and needle back in. I put the old spring back in and put the old mixture screw back in as well as the original slide. I can now get the idle to stumble and drop off, sometimes even a stall, as I lean out the mixture. Adjusting rich will pick up to a good steady idle at about 2 to 2 1/2 turns out, then drop just a tiny bit, but keep running fine until the mixture screw can almost fall out. I no longer have fuel bleeding through the needle jet or at least I can no longer see it. Not like before when there was a steady pulsing spray coming out. I don't know what's going on with this carb, it's certainly not the first time I've rebuilt carbs of all kinds, and this one was double, triple and I don't know how many times checked and re-checked. The sad thing is it was running perfectly before this rebuild with an occasional tiny tweak to idle. Looks like I'll be shopping for a new carb. Anyway, thanks for your help. Know where there are any good deals on S&S Super E's?
