The past few days my justy has been acting up while on the way to work. At first i thought it was moisture in the plug wires, so i greased them up with dielectric grease and put them back on. It ran great that evening, but the next morning while on the freeway i had to go full throttle, or it was going to die. What could this be. The plug wires are good and dry, the plugs are new enough, and look fine. There are no vacume lines off or loose. Granted the temparature has been about -10 F overnight, and barely topping 0 F in the daytime. But it handled a week of it fine before it started giving me problems this week. I need help asap!

Phil, I had similar symptons twice on my '89 JUSTY... The first time was moisture actually inside the cap. Since I had replaced the cap and rotor not more than a month prior, I simply wiped out the cap with a lint free rag and touched the contacts slightly with 250 sandpaper. 'Sputtering' was gone. A few months later a little bit different 'sputtering'/hesitation started... after a few look arounds it wound up being the fuel filter that I'd been putting off. On swapping the filter and running some fuel cleaner through the system all is currently running pretty smooth. (Note: the fuel filter on the 2nd Gen bodies with carbs is on the driver side... if you look under the vehicle between the back of the driver door and where the fuel door is, you'll see a protective plate... undo 3 - or was it 4?? 1 of mine was cracked - bolts and you'll see the fuel pump and filter mounted on the reverse side of the plate.) WARNING: Spiders like to make webs and such in that nook. Best Luck and Skill, #891989 Subaru JUSTY RS 4WD 126, 216 miles

Update, its getting worse, I can't really afford to damage the rusted fuel lines around the filter which is why I am so worried about doing that replacement, but the car is worse than before.

Phil, It could be some other problem, but if you try for the fuel filter swap, it shouldn't muss up your rigid fuel lines... No threading or direct connection to the metal fuel lines... should just be rubber hosing and 'quick release' (plier press) clamps. Just squirt the joining areas with a little WD40 or just a spritz of P'Blaster, so that the rubber hose is easier to pull off. If you have a set, one of those rubber jawed spark plug wire removers works nice to grip (loosen by pulling while slightly rotating back and forth) the rubber hose without damaging. (Otherwise just put some masking tape around the jaws of some needlenose to grip 'em). Have a bit of extra hose and a few extra same/similar clamps handy in case the originals are brittle. Remove just one at a time and note the in and out arrows on the new so as to maintain the proper flow direction. The filter should be under 10 bucks (for plastic replacement). I've overcomplicated this... its really pretty straight forward. If you're nearby definitely give me a shout. We'll swap it in under 15 minutes. Let us know how you make out, #891989 Subaru JUSTY RS 4WD 126, 701 miles

I'm in Wisconsin, thanks for offering the hand though. Finally got around to it last night. One of the rigid lines had to be almost rusted through by the tank, because even being very gentle, it broke right next to the tank. So now I JB welded somthing to the side of the tank so i can hook up some fuel line, I also replaced the spark plugs in case that was part of the problem. We'll see what happens today driving to and from work.

It can't hurt to give your carb a good drink of carb cleaner. There are types you can dump in the gas tank (car will run like crap for that tankful of fuel), and also spray type that you can spray down the carb (while running, follow instructions on can), and also spray down the linkages.

The carb cleaner in the gas tank is in it. Given the fact that the line broke that easily, and we have randomly smelled gas for awhile, but just ignored it, I think that line being cracked has alot to do with the problems. I'll give a few squirts down the carb as well while running as you said.

i really hope you have a fire extinguisher in your justy.
with cracked/breaking/leaking gas lines it sounds like you are really risking going up in flames!
be safe!

No fire extinguisher, if she lights, I'll just stand back and enjoy the fire, this care owes me nothing for how much I've beaten it over the last 30,000 miles.

Alright here's the update from the weekend. In order to solve the gas tank issue, a 15 gallon RCI fuel cell has been placed right behind the back seat, and plumbed into the system with a new fuel filter.
It still spits and sputters randomly. We found the vacume lines on the dist. cap to be loose, so we tightened those up by cutting the hose back so its a snug fit. Now the car atleast dies when you stick your hand over the carb. Full throttle is great, but anything in the middle range is awful, and the idle needs to be set to 1500 to keep it running. spraying the backside of the carb with carb cleaner makes the idle smooth out, wiggling the accelerator pump also smooths out the idle. spraying carb cleaner on the pump smooths things out, as well as spraying the back of the carb in general with cleaner. If i remove the vacume line from the top of the vacume pot on the dist cap, it runs worse, the bottom one doesn't really affect much if i pull it off. I also tried disconnecting the 02 sensor, but that didn't affect anything in a 5-10 min drive. Before we snugged up the vacume lines on the dist pot, the car would smooth out when a hand was placed over the carb opening. So right now i'm really confused and frustrated, and just want the car to run right. It now has a new fuel tank, and all new fuel, new fuel filter, spark plugs, the spark plug wires are less than a year old, the air filter is good.
I'm gonna be bald soon from pulling my hair out over this. lol

Not sure why spraying the back of the carb would make it better. Only thing I can think of that is back there are vacuum lines, your idle adjusting screws (mixture and speed), and the wiring harness connector for the carb.

Alright, does anybody have a carburator that works which they are willing to part with? And how much would it take to part them of said carb, or does someone have an extra one of unknown condition that I could get for less so I an take it apart to learn and hopefully make a functional carb?

With all the rust from the tank & lines,, I am sure there is plenty of trash in the carb. I would clean/rebuild/replace it. ALSO, blow out all lines from the new tank to the carb.I would also, add an extra in-line universal fuel filter near the carb.

We'll see what this weekend brings, We're looking at another car, which would allow me to pull the Justy carb apart and clean it, otherwise i need to have it running period even if that means running like crap.

The filter back by the fuel pump should catch most of the crap up to that point. If there is stuff from the line past that point, there is also a small filter/screen under the float valve seat that should catch it. I have a scan of a blowout of the carb assembly if you want, you can also refer to the carb mod thread in the engine section.

Alright there is an extra vehicle, so the carburator comes off this weekend, and will be rebuilt as i get parts for it. I found a rebuild kit on parts america, if there is any feedback on this kit, it would be mluch appreciated.
