You'll find this to be the best place on the internet for anything Subaru related!
Sounds like you have a Hitachi carb...
I'm sure if u do have a hitachi, most here will tell you to SPFI or Weber it... let me tell u,...
I weberized my 84 gl wagon (just this past week as a matter of fact...), ... worth every penny! Idles like a dream and purrs like a kitten...
I was sick and tired of tweaking the Hitachi to get it to run half-way decent... After Weberizing it, it's like a new engine... it really brought the EA81 to life...
Tell us what you have under the hood and I'm sure you'll find a wealth of information in the replies... do you have a black or blue kidney-bean shaped air filter housing?

maybe choke related?
How does it run when it's not warmed up... rich or lean?
Does adjusting the idle mixture and idle speed screws help at all?
You mentioned rebuilding the carb... i presume you adjusted the float level to 10.5mm (7/8"), or close to that...
Shot throttle bushings can be a major vac leak... with my hitachi, this vac leak wouldn't appear until the engine got hot... then it would be a PITA to get it started again when all warmed up...
Just throwing things out there... hoping General Disorder will chime in here soon... GD has helped me out tremendously with these stupid HiCrappies... I know it stinks waiting for a reply, but it's the weekend and you should get a flow of answers and suggestions here soon... hang in there...

Im not sure what you mean but perhaps you simply need to up your idle speed.
"and when i press on the accelerator it jumps"

Bump for the Carburetor Gods to chime in...

And i meant my one FF. The fuel filter gets air in it when it sits not running???
There are two FFs. One on passenger's side, under the car by rear tire, and the other is under the hood, driver's side. What do you mean the FF is getting air in it?

Change the filter at the back, see if that helps. It cured the '85 BRATs jerkyness. It's symptons were like yours. Idle good, drove down the road good unless I wound it out to long going thru the gears, then it woould start the herky-jerky stuff. Changed the rear filter and it was good to go.

Ok so i think i found the vac problem. but now when it warms up it idles great, however when pressing in the accelerator the engine has a dead spot at like 2000 rpm. ummm?????? EGR???
It's not transitioning properly to the secondary barrel. Possibly the accelerator pump is not functioning or the throttle plates aren't set correctly for the transition ports (or they are blocked).
Stop blaming things on the EGR. They are not responsible for running issues unlesss they are stuck open (huge vac leak). They nearly always are stuck closed and function effectively as a block-off plate under such conditions.

you can always do the mod to keep 2nd barrel open, bypassing diaphram (which sounds like it's shot)...
Btw, my carb was already setup with this mod when i got it. It passed emissions with it!
But eventually I had to weberize due to a few other major problems with the Hicrappy carb.
I suggest you weberize it... it's soooooooo sweet!

Try playing w/ idle mixture & idle speed screws. Idle mixture screw is on front, lower screw, maybe a roll pin in front needs to be removed beforehand, but sometimes already removed.
Good luck & keep us updated on ur progress.
