ea81 carb issue

[turbo5speedgl]

i have a single barrel carb on a ea81 and when i give it throttle it chokes for a second and i have to let off then give it another rev and it will run fine untill i let off and try to go again it chokes.

You have a carter/weber - they have a number of problems. One of which is a tendancy for the bolts that hold them to the manifold to loosen which can cause a vacuum leak. Bogging durring acceleration can be a symptom of a vacuum leak.

The bolts are good I even checked for that leak but its fine. My friends 80 brat has that leak but his just idles high it doesnt bog. Before I looked at my carb it idled high but it was a unconnected hose and I plugged it back in and it idles fine now but still bogs.

the plug on the back of the carb I un plugged an it revs up great but wont idle till warm and then it idles high. i plugged it back in and idles great but chokes.

Unfortunately there isn't a lot of knowledge about those carbs - they were uncommon and generally are even more hated than the Hitachi's which were much more common. I don't know what to tell you other than you should probably rebuild it or swap it to a Hitachi manifold and a Weber.

 

You might try to buy a book on carbs in general to get an idea of how they function and what the ports you are looking at are supposed to do. If it were in front of me I could likely fix it but working blind I can't do much to help you.

Ive owned all three going from the one barrel to the hitachi to the weber. The one barrel is a terrible carburetor. Mine was a low mileage unit and would not run right until the car was fully warmed up and even then it never ran 100 percent. Also i should note that i got better fuel economy with the hitachi than with the carter weber. Going from the hitachi to the weber i didnt really lose much gas mileage but i gained reliability and ease to work on. If it were me id pick up a hitachi intake and ditch the one barrel. There really is no gain in keeping it.

i feel like an idiot i didnt really think when i looked at it but i checked it out again and it is the 2 bbl i just didnt see the barrel under the choke. so could the electric choke be malfuntioning or the anti diesel

Could be a combination of things - vacuum leaks, improper idle speed/mixture, timeing, bad accelerator pump...... The Hitachi's are notorious for the "bog" off idle.

 

Rebuild the carb and check all the tuning settings.

Did you come up with any solutions to the Carb? I have same issue on an 83 GL. Looking for some solutions that worked vs trying a ton of suggestions.

Thanks.
