it will idle with the choke pulled and then slowly pushed in. But if
you go half way it act like it leans out. I pulled them off and all the floats are set just below the seal tops. About 1/4 to 1/8 inch. I have balanced the carbs and the timing is set
spot on. I took apart the pit cock and cleaned it out. And also I have tried running a direct line from the tank to the carbs.
Realy I have a 9mm pointed at it as I type. Help is needed.

Many perfectly clean carbs have been instantly fouled by an initial onslaught of grit-laden or otherwise cruddy fuel.
Good Luck!

Primary Main 62, Secondary Main 135
and
Primary main 70, Secondary main 140
If your jetting is either of these or in between then it should run ok and you should'nt have the problem you describe. Otherwise I would think there is some internal blockage. Those carbs have some tiny passages that I've had to poke out with fine wire or nylon line.

i think you mean wiredgeorge,wireguy is my alter ego! :laugh:Ok I bought my bike from a close friend. He had wire guy build him this set of cv34's for the motor and mods on the bike. But here is my problem
it will idle with the choke pulled and then slowly pushed in. But if
you go half way it act like it leans out. I pulled them off and all the floats are set just below the seal tops. About 1/4 to 1/8 inch. I have balanced the carbs and the timing is set

Still recovering,some days are better than others.

I don't understand. If the engine is cold you start it with the choke on then move it to what ever position it idles without overrevving. Then when it warms up you turn the choke off. Why would you need to operate the bike at half choke if it idles ok with the choke off?

Assuming there's an ample supply of good fresh fuel in the tank.
If not already done, would now also consider battery, spark quality and compression testing.
Would next check battery fluid levels, re-charge it, and check specific gravity. Assure terminal connections are clean and snug, including negative cable attachment to ground at rear of engine.
Ignition spark quality --- would remove spark plugs and visibly inspect spark quality on each cylinder.
While spark plugs are out, would perform compression test. Remember to hold throttle full open during testing.
And install four brand new spark plugs. Guessing NGKB8ES but might be B7ES.
Given properly-timed quality spark and acceptable compression (with correct cam timing), plus ample clean fresh fuel flow into carbs, and clear free-flowing air supply, diagnosis might thereafter point to carb internals. However, I would remain exceedingly reluctant to disturb the rebuild settings as provided by WG.
Good Luck!
