Carb Troubles Autolite 1100
Posted: October 12, 2017, 8:39 pm
Hi friends!
Long time listener, first time caller.
I'm having some issues with my carb. I have a 1963 F100 with a 223 I6 engine with a manual 3 speed transmission and the carb I have on there is an Autolite 1100 which (after some googling) I've decided probably came from a 1964 Galaxie. (The number on the carb reads C4TFE, but I'm assuming it's the same as the C3AFA)
I'm having an issue trying to get it to idle right. I can't seem to open the choke completely unless the idle speed is set really high, and I can't get it to idle at all at 475 rpm, which is what the book says it should be at. At first we thought that the idle circuit might be clogged so we rebuilt it and cleaned every little hole in it. I've tried checking for vacuum leaks, which is what it kind of feels like at times, but there doesn't seem to be one. Everything on the ignition side of things is new and works great, timing was also checked and looked good. So my last idea is that I have the wrong main jet size on there. I just took it out and it looks like its .065. Does that seem right? I'm thinking it's too large maybe?
Has anyone had any similar experiences with these carbs? Any ideas of other things I should check? What would be your best guess for main jet size on this thing?
Thanks everyone!
