Keep in mind you only need spark, gas and timing to make a Model A run. Make sure you have all three, and then start throwing money at other potential problems, like radiators. You don't need a thermostat. And finally, as you work on your A, don't throw anything away, even if you think it's broken or doesn't work; you never know when you'll need it or want it for some other purpose. Welcome to one of the best hobbies there is.
