Likewise, if your secondary butterflies were pulling open, which is doubtfull, you may be letting too much air in. This is where an Electric Choke is nice. You pump the pedal slightly to engage the Cam & start the engine. The electric choke, if adjusted properly, slowly starts to open. By the time Its open all the way your motor should be idling properly, with the fast idle cam disengaged.

Its not fully closed, just partially. Was still playing around with the right amount. I have vacuum secondaries and assume they are closed, but haven't verified.
