Alright everyone, the issue has been solved and it was a very simple one at that. The carb tuning instructions that my weber came with skipped a step. I looked up some generic carb instructions for a different weber model and compared them to mine. Evidently before starting the vehicle the first time I needed to hold the butterfly completely open with my fingers and then rotate the linkage fully. This set everything in place. Now the linkage touches the set screws that its supposed to. After some slight tuning, the Brat idles normally. Now I just need to put the air filter back on, reconnect the accelerator cable, and take it for a drive. I will be adding a throttle return spring for the added benefit based on your feedback though. Thanks!

Thanks for the feedback everyone! I don't believe adding a secondary throttle return spring is going to help with this situation. None of my linkage moves when this issue occurs; only the butterfly opens (I hope I'm getting better with the terminology). I tried to video what was going on: Attached are pictures of the vacuum lines I capped off - can anyone tell me if these were correct? Maybe I capped something I shouldn't have or misconnected a hose? Please correct me if I'm doing something wrong, unsafe, or dumb. Part of the reason I bought this awesome Brat is to learn by doing! I expect to make mistakes along the way. Thanks for all your feedback so far!

Okay, not necessarily redline, but it goes straight to redline. Theres no tach, so I can't comment on RPMs. The choke is electric and I confirmed it has 12v switched power with a multimeter. I do not know how to check it. I do not know how to check for vacuum leaks, but I have capped off all unused lines from the original setup. Throttle return spring? I left everything on the way it came out of the Weber/redline box for the ea71. Let me know what to look for and ill describe it!

Hey guys, just put a weber carb on my 79 Brat. Found quite a bit on here by searching but no definitive how-to guide for putting a weber on an EA71. Well, I got everything connected and fired it up for the first time and it goes wide open! I have to shut it off immediately. I did some adjustment of the set screws with no luck. The throttle cable is disconnected so that's not causing the problem. I am a novice with carbs, or anything under the hood for that matter. Does anyone know what could be causing the issue? It's fully closed until I turn the key to start.

I've been the owner of a '79 Brat for a little over a week and have started building up my wish list. If you have or know where I can find any of the following items, please let me know! OEM Roll bar OEM Wheels Windshield Windshield gasket Back glass gasket Driver & passenger window gaskets GL grille Driver Door card (black) Carpet (Black) Pedal set (manual trans) Back Subaru emblem Seats (black) Steering wheel (black) Lock & key set (doors, glovebox, ignition) - mine are mismatched! I'm sure there's more, but this is it for now.

I also need gaskets for all glass on my first gen. Keep me in the loop if you need bodies for a group purchase. If you know a site where I can get my own, that'd b be great too!

I'm looking for wheels in good condition and an antenna! Zip 19720
