Carb Problem

I installed a 2 inch PowerMadd riser #45430 and had to reroute the throttle and choke cables. The cables now have adequate freedom and work normally. The bike had not been started in over a month, and I didn't try to start it before the modifications.
It starts and idles happily forever on full choke, but dies when I move the lever off "full". It appears that the only fuel it is getting is via the choke/enricher system. I put some strain on the choke cable prior to rerouting, but it appears to work OK. Anyone have a suggestion other than trading for a Harley?

After it warms up a bit with the "choke" ON, what happens when you open the throttle?

Can you maintain engine operation with an open throttle?

If so, I'd expect a clogged pilot jet.

If it won't run at all without the "choke" ON, could be a diaphragm air leak.

Opening the throttle kills the motor. What could cause a diaphragm leak if I have never opened the carburetor?

Unlikely event, but . . . deterioration (resulting in the equivalent of a tear or puncture) of the diaphragm fabric . . .

You may have the "ethanol pox," some passage in the carburetor honked up with ethanol residue . . .
