I was just commenting on the number of turns. I don't think the pilot screw setting can cause your problem.

I have had problems with bench synced carbs on the in line fours where the set up is totally wrong and either too closed or too open to allow a start, just a comment as i have never had a set of wing carbs that far apart!

No, it won't, may not idle smooth but it should start .

Are you sure you set the floats properly? Never saw Randakks video but I assume it has detailed instructions.
Yes, I took care in setting them according the video. Thanks for the question though. I thought about draining the bowls and seeing if that helps initially, What can stop fuel flowing other than the float needles and air/fuel needle jets? I want to try to eliminate all possibilities before I remove the carbs, again.

Plugged passages.

Plugged passages.
What passages that would block fuel from all four plugs? I removed all the jets, cleaned, blew air through them, cleaned all the other parts and reinstalled correctly with new gaskets, etc. Any harm in shooting a small blast of air through the air hoses? Trying to think of everything before pull the carbs again and start over which I'm not really looking forward to do.

Did you clean and confirm all the passages leading from the jets into the carb bodies are clear? Like the passage from the low speed jet to the mixture adjustment hole for instance.

Yes I cleaned every passageway with carb and brake cleaner with pipe cleaners and compressed air. I just tried spraying fuel down the intake while cranking it w/o success. I then sprayed fuel down the plug holes w/o success. Not even one tease. And still no fuel to the plugs. I've got new coils and wires which I'll install but I still need to figure out what's blocked to all four plugs. I checked the carb bowls and all had fuel. Open to any suggestions before pulling the carbs again.

A couple of times people have asked if you tried squirting fuel into the intake but you've not answered them.
It seems like a logical test.

Another thing that puzzles me is; if you have fuel in the bowls, how can it not be getting through the jets into the cylinder?
A very low fuel level in the bowl? How did you set those floats?

And, have you confirmed that the linkage is working correctly?

I asked before if it has compression, that is pretty critical since it won't suck fuel into the cylinders if it doesn't have compression.

I tried this yesterday by spraying fuel in the intake and also in each cylinder. I used a mister bottle and am wondering if that was enough. I'm old enough to remember squirting starter fluid into a car carb to boost it to start. Maybe I need to "squirt" more fuel and see if that helps. I took care in setting the floats per Randak's video. I used a small micrometer with the entire unit standing on end and bending the tab that controls the distance the float drops. I think they're pretty close.

I will do a compression check today and reply. Thanks to all who have replied. Greatly appreciated.

About 2 full eyedroppers of fuel into each sparkplug hole and thread the plugs back in. If there's compression and spark, it will run about a second or two on that fuel.

Sounds like you have no spark. Like has been said, it would run for a bit even with the carbs removed, if you squirt a little gas in the intakes or cylinders, as long as it has compression and spark.

Squirting into the cylinder is a waste of time and fuel. You need to squirt some fuel, or starter fluid, into the intake as you push the start button and the engine spins. And yes squirt! Misting is for house plants.

Compression test, 90# on all cylinders, keep in mind I bought new in '77 and has only 50K miles. Always ran well until gas issues and starting last September. I pulled carb unit and rebuilt using Randaks parts and video. Followed every step and am confident I assembled it correctly. New cables and installed correctly and linkage is correct. I shot and ounce of fuel in each cylinder and got a blip. I then again removed filter and sprayed fuel down intake. No fire and no fuel at plugs. Next step?

90 pounds is too low. Even with the cold motor it should be higher. Did you have the throttle wide open?

An ounce of fuel is about 100 times too much, amazed you didn't get a hydro lock. Are you sure the plugs are firing & in time?

I also pumped in 15psi into the carbs using the output line of the fuel pump, held steady. Not sure if that means the carbs are pretty well sealed, no leaks.
