Shelby;
My carb has no choke either,what I do is after starting the car (it starts on the first crank),I hold the rpms at around 1200 till
oil pressure comes up,(it comes up reaalll fast,luckily)after about thirty seconds or so,I put it in gear (forward or reverse,does not matter) and let off the clutch and roll the car a car length or two,making it pull some vacum,after that I can let it sit there and idle till it is fully warmed up before taking off....
This little trick works on my car well and I do not have to sit in it and hold the pedal to keep it going.... Usually I go in the house and get ready to go were ever I'm going,letting it idle for 3 to 5 minutes sometimes more depending on the outside temp, before leaving.... I live out of town a couple of miles and only about 200 yards off the main highway,so after leaving in 200 yards I've got to get up to speed or get run over and I do not like revving up a cold motor,especailly with 9 quarts of cold
oil in the pan....
