I was out in the foothills this morning (where it is much cooler) and noticed that I had to blip the accelerator to get my idle down from 1500 to 900 rpm (Holley 3310, electric choke, vacum secondaries). I also noticed that my mpg was way off for the day. What I discovered is that my choke was not opening completely, however, once I got back down to the flat lands where it was a little warm and more stop-n-go the problem went away. I started thinking about this and remembered that I installed a 160 degree thermostat. I'm thinking the engine isn't staying at a temp when it is cool/cold to operate the electric choke properly and I need to bump up the thermostat to 180. The puzzling thing is, I've never had this problem before today.

Any thoughts on this?
