RE:4100 secondary probs?

You've got your question stuck in the middle of a nearly two year old thread Jeff! The only reason I spotted it, or looked for it, was because I got the e-mail notifying me of a response to this ancient thread.

So I kind of doubt many are going to notice. But I'll give you something to check and maybe others will jump in and give you other ideas.

You're saying the secondaries of your '66 bird's 4100 Autolite 4V are not kicking in - "inop."?

Have you inspected the secondary diaphram carefully looking for cracks/tears in the rubber? The 4100 is a fairly simple carburetor with adjusting the floats during the rebuild being the only moderately skilled procedure. If your secondaries are coming in, definitely check that diaphram.
This thread, so far...
