carb problems

[kzman]

I have a 78 KZ 1000 Kaw & I'm having problems with the carbs., they are the 28mm Mikuni's. I have compleatly tore them down 4 times, put them in a ultra sonic-cleaner and they look great, But, once I put them back on the bike and the engine is cold I can not get the choke to work. I can get the bike started if I spray starting fluid in the carbs & once the bike is warmed up it runs great as-soon-as the bike cools down it will not start. The choke plungers all look good, the O-rings look good, I've used an air hose through all the ports and everything looks clean. It just will not start when it's cold.
Please advise anything will help

Low float levels ??
Or something else causing the bowls to go dry......or almost so.
Does it have a stock air cleaner on it, securely ?? That helps too.
Are your idle air screws turned out about 2-1/2 turns ??

And lastly be sure you have a healthy battery that is fully charged.
Sometimes a weak spark will fire starting fluid (ether) but not gas.
