No fuel to cylinders. None. Zip. Nada. Dry plugs.

No matter how you do the actual dipping, you need to ensure that all of the tiny passages are clear afterwards. A spray can of carb cleaner with it's red straw will do. You need to visually inspect the spray pattern around the pilot jet area, several transition holes from the pilot jet into the carburetor bore, the holes in the side of the choke intake pipe, in short all of the air and fuel passages on the whole carb, make sure all four of them are identical. Giving the jets a good going over with the spray is good too, the dip loosens stuff but doesn't necessarily move it out of the way.
You will definitely want to wear safety glasses for this.

Will do, brother.

Nessism, thanks. My carbs are VM, but some of the stuff in that rebuild is helpful nonetheless. I followed a rebuild procedure on BassCliff's website when I did mine, although I skipped the float check. I'll do the float check when I pull them back off.

Hie thee down to the local Walmart or Autozone or O'Reillys and get a gallon can of dip and follow the VM tutorial

It would seem that:

1. Either you didn't follow the tutorial, or
2. You broke the screws off, indicating a lack of attention to detail

I don't see where you out new O rings in the carbs

Clearly, if there's gas in the float bowls and none in the cylinders, your carbs are clogged

15 minutes in boiling pine sol didnt loosen up chit inside them..in my opinion of course.

There are also rebuild procedures for the VM carbs on Basscliff's site

One more thing you might want to check is if the plug wires are on the correct cylinders.

Well I took the carbs apart again, completely, and sprayed carb cleaner through every passageway. There was indeed some slight blockage but it's all cleared up now. I didn't find anything completely blocked, so I still think there's a problem elsewhere.

Put it all back together, but it still won't fire unless i pour gas in through the spark plug hole manually. I do appear to be getting fuel into the cylinder, but it isn't burning it. I do have spark.

The plug wires are on the correct plugs per the labels on the wires. I changed the points out and there was no difference so i gave up for the night.

Maybe the timing chain is broken?

Thanks

Got it running. It took about 6 cycles of starter fluid. I think the valves were dirty or something, but it starts and runs on its own now. Thanks guys.

So this had nothing to do with your carbs? 6 cycles of Starter fluid?

thanks

I see that you have the problem resolved (well, at least the bike is running), but still feel the need to insert a comment or three.

Passages don't have to be "completely blocked" to cause problems.

The plug wires are on the correct plugs per the labels on the wires.

Do you really trust the previous owner(s)?

You really expect that, after 30-some years, those wires are still correct?

Unless something has been changed, the left coil will fire plugs 1 and 4, the right coil will fire plugs 2 and 3.

Maybe the timing chain is broken?

If the timing chain were broken, we would not have seen this in the first post:

All of my compression values are at least 100 psi ...

And that would have been easily confirmed when you adjusted your valves.

You did adjust the valves, didn't you?
