Bill is correct, all about closed throttle airflow. Often takes a long time to get them juuust right.
You were mentioning them on a 289, is why I thought you might not get them to idle low enough (I might have been confused on that)
Not a 289. A 347 with a C60A T/A manifold.
The plan A, is working on the throttle plates for today. The idle circuit on the 4180's went away again and an executive decision has been made by me to release them to boat anchor usage. I'm not going to waste more time on them. A dozen times into them is too much.
If I can get the 3300/3301 to idle down to 850 or so I'll be happy. Granted, info on my application isn't a snap to find but then again, I always did create my own problems?
Why take the easy route, anyone can do that? What else would I do, read a book?
I just needed a little encouragement to continue on the BC/BD's, which you all gave me, so thank you all for that.
I'm not sure when stubborn clearly changes over to stupid? I'm sure, "I'll be the last to know"?
Hey I fixed the Webers. A five pound "lumping hammer" was all that was needed! You just hit them a little here and a little there.
