bogof Posted February 2, 2009 Share Posted February 2, 2009 (edited) I just picked up this. Obviously it's beat pretty bad. I'm just using it for some local tough truck races. My problem is I can't get the engine to open up. I get good throttle response at 1/4 throttle, but after that it sputters and dies. I have been reading about these engines, and I heard that the weber upgrade is a good one so I was thinking of switching. I popped the hood and looked closer at the carb, and this is what I found (I know the engine bay is filthy). It's stamped weber, but it has the stock Subaru filter and airbox. Is this the right weber carb, and if it is how do I liven it up. I have searched for a few weeks, but I don't know carbs very well. I'm sure this has been covered before here so I'm sorry. My searching never really gave a good link on how to tune this carb (if it's even the one I think it is) Another problem I had was water and oil getting into the airbox. I took off the hoses that ran into the airbox and found that the one leading into the pass side of the header(?) was the one kicking the milky oil into the airbox. edit... I am also trying to lighten it up but can't get the rear window out without breaking it. Is there a trick to get it out? I want to sell anything good on it to recoup the cost of the brat. Thanks for any help. BTW the brat did great at the races. Even with the engine problems it still placed first in the 4x4 light and 3rd overall!

Twitch de la Brat Posted February 2, 2009 Share Posted February 2, 2009 I believe that you lost an EGR valve. Mine did about the same on the driver's side. Just unplug the hose that was blowing the crap in there. It should do just fine without it. As for the carb, I would just recommend cleaning it out while the engine is cold and off. Hope it helps!

Suberstar88 Posted February 2, 2009 Share Posted February 2, 2009 dont know about the older boxer engines, but the ea82 is very vacuum dependent, so check youre vac lines and stuff. Link to comment Share on other sites More sharing options...
monstaru Posted February 2, 2009 Share Posted February 2, 2009 that is not the weber 32/36 carb. that is a carter/weber carb. the 32/36 upgrade is well worth it.especially if you are going to race it.cheers, brian Link to comment Share on other sites More sharing options...
Bucky92 Posted February 2, 2009 Share Posted February 2, 2009 That doesnt look anything like the Weber thats on my coupe...almost looks more like the POS Carter Weber that used to be on it...which I sent sailing through the yard. Does sound like it has a clogged jet and from the looks of the motor ..I wouldnt doubt it. This was my carter weber..minus choke cause some shmuck cut it off when it stopped working: and this is the Weber that we all talk about ..Note its a 2 barrel carb I am not the most up on the carbs but it looks like you have the dreaded Carter Weber ...and IMO ..they are aweful..no power and bad milerage..

bogof Posted February 3, 2009 Author Share Posted February 3, 2009 OK so I got a lead on a new 32/36 weber. Anyone know how to remove the rear glass without breaking it? Also is there any part that is usually wanted by people trying to keep these clean looking? I have several parts I have taken off that I am looking to sell(on here).

mcbrat Posted February 12, 2009 Share Posted February 12, 2009 when switching to the weber 32/36, you will need to find a different intake manifold. the weber adapter only fits the hitachi manifold, not the Carter/webber. Link to comment Share on other sites More sharing options...
edrach Posted February 12, 2009 Share Posted February 12, 2009 (edited) Others have identified the carb as the single barrel Carter-Weber. You might be able to get it to run better by replacing the fuel filter (next to the fuel pump on the driver's side near the rear wheel; on a metal plate bolted to the underside of the car) and the fuel/water separater (looks like a fuel filter, but has three ports instead of two). It might run better for you then, but it will be necessary if you go for the two barrel weber carb. Odd, I don't see the fuel/water separater in your pics, but it's right by the windshield wiper motor in Bucky92's pic.

Psyko Posted February 12, 2009 Share Posted February 12, 2009 Odd, I don't see the fuel/water separater in your pics, but it's right by the windshield wiper motor in Bucky92's pic. If it's there, it'll be just out of view because of where the top of the picture cuts off though. I think the tube my awesomely curvy arrow (drawn with a not so awesome ball mouse) points to comes from it. 9] I stole your picture, I'm sorry. My engine bay does look about the same though, but with more oil. Link to comment Share on other sites More sharing options...

Odd, I don't see the fuel/water separater in your pics, but it's right by the windshield wiper motor in Bucky92's pic. Based on the passing lamp/headlight configuration...the fuel pump may be in the engine compartment near where the vapor separator is on later models, but the fuel filter is under the car in front of the rear driver's side wheel. No vapor separator, just the single filter. That is how my '81 hatch is, let me know if you want pics. Link to comment Share on other sites More sharing options...
bogof Posted February 13, 2009 Author Share Posted February 13, 2009 Thanks for all the help. What intake manifold do I need? I will look at the fuel filter, and water separator. It is a blast to drive in this weather. Here is an updated pic. Link to comment Share on other sites More sharing options...
edrach Posted February 13, 2009 Share Posted February 13, 2009 . No vapor separator, just the single filter. That is how my '81 hatch is, let me know if you want pics. '81 Hatch is different. This is an '82 Brat and vapor separator is in engine compartment and fuel filter is under the car on the driver's side near the rear wheel. Here's pic of our '82 Brat.

TomRhere Posted February 15, 2009 Share Posted February 15, 2009 As for your question on what manifold to use; EA-81 Hatachi carb one is a direct swap. An EA-82 Hatachi carb intake can be swapped on with a bit of work. I'm running one of those on my '86 BRAT Link to comment Share on other sites More sharing options...

bheinen74 Posted March 10, 2009 Share Posted March 10, 2009 you should get a roll cage if your doing that. one bad landing, flip, death. protect yourself with a cage. At least you have the helmet, thumb up for that. fun Link to comment Share on other sites More sharing options...
