carb problem(s)

[LA Mike]

I have carb problems I can't seem to get corrected. I let it warm up and after you push the choke in the has no effect on the RPM's; the idle  adjusting knob is not the problem. What could cause this issue with the Rpm racing w/out the choke out and no stuck throttle cable. What are some of the things I should be checking? Idle circuit, air leak,??

Here is the bike/ carb info:
93 FJ1200
Yoshi slip-ons
Uni's pods
Mains: 117
Needles: stock
Pilot air: 155
pilot jet:37.5
a/f mix @ 2turns

Thanx,
Mike

Mike,

Have you checked that the choke rod (on #4 carb) is moving back to the right when you push back the choke knob?
It could be an air leak, but you'd probably have difficult time starting it if that was the case.
Is there any smoke from the exhaust?  If so, what color?

Cheers,
Arnie
