markjs Posted January 16, 2006 Share Posted January 16, 2006 I have an '82 GL Wagon with an EA81 and it was running like crap after much prolonged sitting. Anyway I had had a spare carb on another parts car that had run fine prior to the car being wrecked so I slapped it on the '82 and voilla! The thing runs a LOT better. Trouble is there is still a midrange hesitation. At around 1500-2500K RPM it's falls flat and picks back up above 2500. Is there some obvious thing I am missing or does it simply need stripped down and cleaned? Link to comment Share on other sites More sharing options...
robaru Posted January 16, 2006 Share Posted January 16, 2006 Have you tried a couple squirts of carb cleaner down the throat of the carb? Other than that It could be a sticky choke, or vacume leak perhaps. How long did the carbs set? Link to comment Share on other sites More sharing options...
markjs Posted January 16, 2006 Author Share Posted January 16, 2006 No idea how long they sat.... Just was willing to try anything to get this goin. I see no choke at all, unless it's only over the primary. Will give that carb cleaner a go and see what gives.......Anyone else with ideas please chime in!

volkswitt Posted January 16, 2006 Share Posted January 16, 2006 you might check the accelerator pump. carb kits are cheap. you might try a rebuild on the carb. Link to comment Share on other sites More sharing options...
exister99 Posted January 16, 2006 Share Posted January 16, 2006 you might check the accelerator pump. carb kits are cheap. you might try a rebuild on the carb. I second that emotion. I have several carbs lying around for my Soob and I always try make sure I have a freshly rebuilt spare on hand in case I need to do a swap. One observation I have made is that with a little creativity and some trip to Home Depot you can make a Hitachi carburetor much for "field maintainable." With a little patience and care you should have no reason to be afraid of diving right in and doing a rebuild. Inspect everything and figure out how it works, your problem will soon become apparent.

markjs Posted January 16, 2006 Author Share Posted January 16, 2006 Is it possible (on a weber or carter, as my carb doesn't seem as complex as the hitachi), to just take the top off with the carb installed and give all the jets a good carb-cleaner hosedown?

Now why would you want to do that? I'm willing to bet it would be less hassle just to pull the thing. If you don't have a spare gasket to reinstall it you can just go buy a roll of the right gasket paper and cut your own. A carb is tedious enough to mess with on a well lit bench. My lower back would be hating me if I tried anything on it installed. Just my 2 cents. Cheers Link to comment Share on other sites More sharing options...
