Thanks Paul. Yep, afraid so, KC4NWF. Will try to send you a picture of my station. I guess private message is best way.I collect tube type Collins equipment. Have a 105 foot tower in my back yard. Some of it is magnificent equipment. Also restored a 1957 Collins kilowatt AM broadcast transmitter that is 7 feet tall and weighs 1200 pounds that was featured in two national journals. I am an orthopaedic surgeon and my electronics background is all self taught. You know, it's all just having a knack for mechanical stuff, especially orthopaedic surgery!! Yes, I am aware that the secondary butterflies in the injector housings have no effect on idle. I had all of that linkage apart when I cleaned the top end. I know that some of you folks removed the whole system. Mine is still functional. Unfortunately, the sealant around the main throttle plates is what I removed most of and had an oh sh-t moment when I discovered that I wasn't supposed to. There was oil in the plenum from leaky PCV cover and I thought that gunk was from that. That's what I meant when I stated that I was disappointed that the machining tolerances were so poor that they used that gunk. Maybe they had to because the manifold vacuum
is so high. My having removed it probably explains why my resting idle is 1100. If someone can instruct me in what to reapply and how to do it, I would be most grateful. I rebuilt that throttle body but knew better than to remove those staked plates. Rebuilt a couple of Quadrajets in my time and a Holley or two. No light leakage around them with them closed, but probably enough air leakage with the throttle closed with the tremendous vacuum to boost resting idle level from 650 to 1100. Is the resting idle of 1100 detrimental and is it worth the hassle of reapplying the "goop"? Thank you for your help! Look forward to hearing from you!
