more power using choke w/o plates?

Awooga.

I don't have choke plates on my webers right now, no big deal. I pulled back my choke at a light the other day, and the engine reved to 3K from it's sub 1000 sleep.

So now it seems like I have 2 gas pedals. It feels like I can get more power when say driving up a hill and using the choke. Is this in my head? I smell more fuel then after some hard acceleration using it. I'm assuming this is the same thing as pushing the gas pedal in and revving it higher in a gear, but if someone could enlighten me as to what's going on, I'd be interested.
