You may also want to look at the fuel vent tubes. AMC issued a service letter for this condition. http://www.amceaglenest.com/~iowaeagl/guide/index.php?title=September_1985_-_IS_34E_-_6_cyl._Engine_BBD_Carburetor_-_Restricted_Idle_Fuel_Pickup_Tubes On Sep 26, 2010, at 9:50 AM, wrambler242@xxxxxxxxxxx wrote: My belief is that the current batches of fuel mix we get is pretty darned good at scouring out gum and varnish. It seems that if the car will run well enough to get through a tank or two of gas the system cleans itself! The killers are. Rust Actual chunks and bits of dirt. Hardening of gaskets and rubber hoses. The dreaded black gunk! That hardens on valve stems and sticks the valves. Once running do the crawl, check and or replace all the hoses! When they are 10+ years old they tend to be hard as ROCK. Replace. I now only buy efi rated hose as all the efi hose I used is fine. non efi rated by the tank on the return was rock hard after only about 8 years!

My vac lines were all ok, and it had run fine last year. I put a bottle of the GUMOUT gold color Fuel system- carb and FI cleaner in and a full tank of gas. Ran through about 3/4 of a tank... it said to run the tank to near empty, and then all of a sudden its running great, won't skip a beat, so had good luck with that. Maybe cleared out a jet, or removed some moisture, who knows, but just a thought. regards. Ken/boston Ray Mick The older I get the faster I was.
