@zackpradel While getting my certificate in automotive technology back in the 90's (keep that in mind), all of my instructors agreed it was best to put the engine under load (i.e., not idling) as soon as possible. Idling is tough on an engine. I'm not sure I still agree with that.
@AmericanVoy3ger @Lambothirteen Surprisingly, there's a lot of companies that sell just about every part for Model As (like Bratton's, Eckler's, and MACs, to name a few).
