Hi,

Well I centered round plates and tightened the screws. On the bench not attached to main unit and not on car, no squeak. Put together , put on car, manually activate throttle - squeak. It changed pitch of i put the throttle to one side. Again there is no play up and down but must be a slight tiny 1 thousandth of a inch right to left in shaft. That is what it feels like.. but you'd never really notice. Again if you push lever ever so slightly into the carb as activating the throttle it must be pushing the circle plates into the bore, or the shaft itself is just super dry.

I'm going to do as Tom suggested and apply some oil to the shaft location. I'm assuming some engine oil is fine. Probably wouldn't hurt to actually remove the whole primary shaft, lubricate and install again. I wouldn't call for a bushing kit on it or anything.

I will go back now that i know a bit more about why it's doing it and try lubrication.

Other topic, I took a pic of rear metering block, i don't see where the slosh tubes would attach, it must be too old.

Have a look.

Other topic, I went back to the big ball. Probably unrelated, I've never had this happen before, has anyone ever had a perfectly good looking diaphragm expand incorrectly? As you can see in the pic, crumpled when pulled down. The spring installed. The rod is shorter then the hook up spot, as seen in pic. Probably normal. I should probably install the spring and top part first, then pull rod down to secondary shaft and attach. I didn't do that and it's operation is not right. Not smooth at all, i know it should be.

MY question is do you put assembly in when the diaphragm is in it's relaxed position? I'm going to try that now. I don't think the diaphragm part # is wrong and the rod length is incorrect but who knows. I'm sure learning a lot, thanks again everyone.
