Have spark, Have gas, Carburetors rebuilt, NO RUN!

where are the pilots adjusted to?

What is the process of adjusting them? I just seated them gently in there after I cleaned them.

That would be No. 1 on the diagram.

Start at 1 1/2 turns out from lightly seated. Roy

oh yeah I have those adjusted, I thought he was talking about adjusting the pilot jets themselves. heh. I found a couple different specifications for adjusting the idle mixture screws they both say start 2 full turns out from lightly seated, but from there one says +/- 1/4 turn and another says +/- 1/2 turn. Even if I'm running rich or lean it should still run. thanks though Roy.

Cleaned the pilot orifice, didn't see anything come out but a good amount of air was coming out of it. Almost got the bike to start after that, we'll see if I can get it going later with starting fluid. How much choke should I put on when starting, and how much gas should I give it?

With cold engine, choke full on, don't touch throttle (leave it completely closed), tranny in neutral, kill switch in RUN position, push starter button.

Did I mention DON'T touch the throttle? :laugh:

Good Fortune!

1 1/4-1 1/2 turns is generally good starting point

How high should my carburetor valves be on the bore side when starting?

if your talking about the slides which i presume you are. they should be all the way down. let me ask you this you said you resynced the carbs how did you do this without the bike running?

I'm still new to this so I may have mistaken the term syncing whatever it means as getting the slides to be at the exact same height from the bottom of the bore. Is syncing adjusting the mixture screws while running?

please forgive my misuse of terminology I don't know any better yet. It's a bit different from chevys lol

Update: It still isn't running, slides on carbs all move to the same height at the same time, and are all the way down when starting. I have good compression, and good spark. Gas isn't getting sucked into the cylinders. I checked this by getting a cotton swab and putting it down the spark plug holes one at a time, spark plugs still in all other holes, and covering the rest of the hole with my finger. There was no gas on the swab, nor when I swabbed the piston itself. Floats all pass the clear tube test, pilot and choke circuits are clear. The rubber intake grommets that hold the carbs on are all solid, no cracks, they are still soft to the touch and new. One thing I'm not sure is supposed to happen or not is that when trying to start the bike with choke full on I get blowback from the choke intake orifices. Whatever is stopping it has to be affecting every carb at once, since it should be able to run even on 2 cylinders. (these arent my carbs, mine are clean. Just an example pic)

I've seen some things about testing the slides with compressed air, do I blow the air in the main jet with the spring off, take the jet out and blow?

petcock good and tank decent inside?.....use some clear fuel line and an inline filter to verify there is fuel in the line.....edit..i just reread your original post....you still have something wrong with those carbs
