I just put the EA82 in my 88 GL back together after a blown head gasket and now the engine runs fine but it's having idling problems that it didn't have before I took it apart (several months went by between starting and finishing, busy with other stuff).
I have drained the tank of old gas and replaced it with about a half a tank of new gas and sea foam, changed the fuel filter in the back by the tank, and blew the carb out with some carb cleaner and sea foam. All of that helped a lot but none of it fully fixed the problem. Basically I was hoping it was just bad gas / something simple that would just clear up on it's own, but it doesn't seem to be.
When I adjust the throttle (the only thing I touched when I took everything apart for the head gasket) so it idles at around 1000, it's fine until next time I start the car, then it's way too low or way too high. Literally just turning the car off then on again. I played with it and cleaned the carb more (without taking it out) and once the car was warmed up and was idling in a more predictable way and revving normally, I took it down the driveway and the accelerator kept sticking, every time I use the gas pedal, the engine only returns to around 2000 rpms until I lift up on the pedal with my foot.
Maybe I have a sticky pedal, throttle cable, or accelerator; maybe carb dirt; maybe something dirty still happening in the gas tank or earlier in the fuel system. I have very limited cash and time otherwise I would be into doing more hunting or taking the time to properly clean the carburetor.
Keep hunting for the sticky gas pedal problem?
Take the carb all the way off and take it all apart and thoroughly clean it?
Or would it be easier to just get a rebuilt carb and replace it? I have only cleaned little outboard boat motor carbs and a motorcycle carb once and I'm afraid of taking it apart and wasting too much time and not getting it back together properly.
Would it work to get a used one off a EA82 at a junkyard / online or am I likely to have the same problem / more issues?
What are other variables I am ignorant to?
I'm new to Subarus and suck at carburetors, any help or advice would be greatly appreciated. Let me know if there are any helpful pictures I could take or any other information I can provide.
