82 22R Manual --Idle up diaphragm hose---where does it connect???

Hey there, where does the Idle up Diaphragm hose go on an 1982 22R Manual Pick-up? I cant seem to find it in any of the vacuum diagrams????
I have looked and looked with no luck. As it sits the diaphragm is just without a hose and I cant find a missing vacuum port to connect it to. Thanks!

Go to autozone.com and become a member. It is free and you can then look up repair guides for your vehicle. It does have a vacuum diagram with pics.

Thanks for the tip! I went ahead and registered with autozone and unfortunately, there is no indication of where that diaphragm hose goes. In fact it doesnt even exist on the diagram. I have the reapir manual for the 1982 22r and you would think it would be clearly stated in there, but it is not.

The issue I am having is this, this is my friends truck by the way, he thought the truck needed a new carb because the truck was running horribly, stalling not idling properly and such, so we replaced the carb with a newly rebuilt one. After doing so we found the truck would run the same. After checking all vacuum lines and finding no leaks, we finally found a ground wire coming from the ignition coil going to the distributor that had broken free, we re-attached it and the truck fired up! After 10 minutes it was choking down and finally just died. We thought the carb may need adjusting but after adjusting the fast idle and mixture to stock, to no avail, the truck was still acting the same, it just will not idle but will run at higher rpm's. We let it sit for 20 minutes thinking it may be thermal related and sure enough,it fired up and ran for about 10 minutes then started choking down again, then finally died.

My bigger question here is, is this thermal related? I noticed I could manually close the choke butterfly and it would run, but then after several attempts to keep it running, it finally died again with or without the choke closed.

We checked the fuel pump and it is getting plenty of gas to the carb. Fuel filter is new. Any ideas here? Thanks!

Got it nailed. Carb was obstructed, one of the plugs was shorted together and carb needed adjustment. Runnin like a top.

Well if ain't broke......

But for curiosity's sake, is the new carb exactly like the old carb....part for part? Sometimes a rebuilt carb might not have a feature because they change from year to year; and they could have sold you one that may fit several model years.
