Too cold to start car

chokes help. But I just started my '85 Ramcharger with a 3310 holley without a choke. In the 20's, 3 pumps and started first lick. 20 seconds of "feathering" it and it idled fine on it's own and I walked away. Idling as I type and warming up. Chokes are important and help, especially when the temp becomes single digits or below.

If you need a choke to start at 20*, and after 20 minutes of grinding, you have another problem. And putting a choke on it is probably going to mask it.

My opinion, of course.
