81 gl1100 still pushing too much fuel in cylinder

Hi, my gl1100 is still metering out too much fuel into the 2 and 4 cylinders. It'll idle on the other side but is just waaay too much fuel to fire until I rev the bike up past 2500 rpms. Then it'll fire but still spray lots of unburnt fuel out the pipe. Anyone have ideas?

Oh, and does anyone have leads where I can purchase the press in slow idle jets for my '81 1100..? Maybe need carb #4 as well.. I see ebay has the screw in jets but not the press in ones... Thanks!

You still have float/float valve problems.
If you will fill in your profile with where you live I'll go look and see if I have what you need. Might bring them to you if you happen to be in my area.

With no God over the state, the state then becomes not the defender of liberty but the definer of liberty.

If I disagree with you it's simply because you're wrong.

You might very well be correct but what can happen is this. It can be very misleading but it happens when a bike is LEAN. The mixture can be too lean to fire. It's getting fuel but lean mixtures are hard to fire. Especially with an older point style ignition system. If the fuel comes in and it is too lean to fire it will just be dumped in to the exhaust where it will smoke and stink like crazy. It can also fuel foul the plugs.
I would try this. Clean all the plugs or replace them. Let the bike sit overnight. With the known good plugs will the bike start with little or no choke? If it starts with no choke it is probably rich. If it starts with no choke does it run better if you create a vacuum leak? (lean out the rich mixture)
If it needs lots of choke when it warms and starts to act up does it like a little choke left on? You have to do these "tests" as quickly as you can. You need to get them done before there is an opportunity to foul the plugs again.This should give you a better clue just to be sure. You might very well be correct about it running rich. Just don't let it fool you. Don't forget basis either. Do the two cylinders in question have reasonable compression? Are they getting good spark?
Dave, are you going to deliver those parts to Oregon? Nice ride from Arkansas to Oregon.

Click on tools, user CP, edit details, then scroll down to add info.
Portland is a little far for a day ride but I'll look for some jets.

Thought I had some press in jets but if I do I can't find them.

Don't think it's running lean. Checked the basics (compression, etc..) and it's all good, set the float with a gas IV to make sure it was cutting flow off at the proper height. At this point I'm dead in the water till I find an idle jet or carb to pull one out of anyways...
