[Tigers] Holley electric choke starting

[Tom Witt]

Since the whole purpose of the electric choke is to warm and thus open it..., and you are having better result with the 10 second wait I’d be incline to say the choke is set a bit too rich. A choke in general is a very imprecise way of dealing with engine and air temperatures.  And if you look at the side of the choke you can see it has quite a range of adjustment. While the electric choke eliminates the heat riser tube or in some cases water tubing it in its own way is even more imprecise. Case being an ignition left on on a cold day without the car running has the potential to open the choke completely when in fact for cold starting it needs to be near fully closed. Thus the electric choke is operating independent of the actual air and engine temperature. the other choke heating methods at least have some correlation to engine/air temperatures.

Question? Does your car have an electric fuel pump?  If so the better starting results from the 10 second delay may be from fuel reaching a depleted carburetor bowl more than any aspect of the choke setting.

A question about starting a car from cold, with an electric choke Holley.

Do you attempt to start the car the instant you switch on the ignition...or do you wait 10 seconds for the choke to set before cranking it over? I've gotten both scenarios from  Holley discussion groups. All I know is that at +50F, the 10 second rule seems to work better- at below that temp, nothing works well or consistantly. This is the carb on my '68 Cougar 302.
