I think the idle eze is a very good thing altho of course they aren't on some carbs and none of the holleys---for years I have been putting a 1/4 npt plug in the center hole of the base plate and drilling a small hole in it for idle air that I get to the center with a small cross milled groove on the top side of the base plate--it usually takes from an .085 up to .125 depending on engine and cam size--i have been able to get a steady idle at around 850rpm on most engines and that is low enough that the mech advance hasn't kicked in and the engine will shut off without dieseling---most times also the idle mixture screws will be at 1 1/4 turns to as little as 7/8--never had to go past 1 1/2
We also take the feed wire for the fan directly to the alternator like you except we do use a relay to turn the fan on and off---
I noticed going back and reading all this thread that initially with the pic of your radiator that you said it was a 3 core(post 12) and later a 2 core (post 68). Is it a 1 inch tube or a 1 1/4 tube and how many fins per inch???
Glad to hear your making progress
