Airborne Posted July 31, 2012 Share Posted July 31, 2012 I recently purchased an 86GL (EA82) wagon that I would like to do a little work on. One of the items I'm considering is a Weber carb as this vehicle seems a little doggy in the low RPM range, but before I do that I would kind of like to know what I am replacing. Anyone recognize this unit? Is it the stock carb? I can't find any markings that would indicate a brand or model. Quote Link to comment Share on other sites More sharing options...
naru Posted July 31, 2012 Share Posted July 31, 2012 Non stock. Holley 5200,I think. I see an ID tag w/#s in the 2nd photo. Quote Link to comment Share on other sites More sharing options...
Airborne Posted July 31, 2012 Author Share Posted July 31, 2012 Right, there are markings in a couple of locations, but nothing that makes sense to me. The tag in the second photo reads... L7760 3460 On the front (center) it reads A-2 and at the base it reads R7760. On the left side it reads B-2 and 2F 5675 B On the right side it reads D-3 Nothing that I can see on the rear, and nowhere do I see Holley, Webber, Hitachi, etc. Quote Link to comment Share on other sites More sharing options...
naru Posted July 31, 2012 Share Posted July 31, 2012 (edited) holley r7760 version of a 5200 ? http://www.carburetion.com/CarbNumber.asp?Number=R7760 Edited July 31, 2012 by naru Quote Link to comment Share on other sites More sharing options...
Airborne Posted July 31, 2012 Author Share Posted July 31, 2012 Studying the diagram you sent, it would seem that your first guess was right... a Holley H2-5200. Further investigation tells me that this carb was modeled after the Weber 3236... I wonder if I shouldn't just work with it a bit? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted July 31, 2012 Share Posted July 31, 2012 Holley 5200 for sure. Holley licensed copy of the Weber DFV. They kinda suck - different venturi sizes depending on application make them a chore to tune. You can't just use what someone else used as a baseline jetting.... They should accept standard Weber jets though. GD Quote Link to comment Share on other sites More sharing options...
IASUBE Posted August 1, 2012 Share Posted August 1, 2012 I've had pretty good luck with them on my EA-81's.. Like GD said they had at least 2 different versions (cfm wise). I try to stay away from the electronic ones, but the one you have doesn't look to be one of them.. In the 70's and 80's all of the big three US manufacturers used them on their 4 cyl's. They're not as plentiful at the U-pull-it's any more... But that's where I got my stock of carbs and tune up parts. Kits are cheap last I checked and there is a wealth of info on the net about tuning them.. Weber jets may fit as well GD mentioned. I'd try working with it a bit if you have the time... when tuned the butt dyno would not be able to tell the difference from a real Weber.
