83pickle Posted September 7, 2011 Share Posted September 7, 2011 My ea81 is having idling issues pretty bad. I kick the throttle to let it fast idle to warm up, but all of a sudden, it doesn't idle properly. I adjusted the idle screw to a nice rpm and then go on my way and after awhile of driving, i stop at a light and it idles down to nothing and stalls. I have to keep my foot on the gas to keep it running. I have adjusted the idle screw about 4 times now and it seems like it should be racing. What should I be looking for? The last thing I can recall doing was filling up at Chevron. That's all I ever used in this car. Link to comment Share on other sites More sharing options...
ruparts Posted September 7, 2011 Share Posted September 7, 2011 hi, sounds like the fast idle screw ( hard to find its in the back )_and choke release may need some adjustment . especially if it has a cooler temp thermostat than original. you need to set the main idle when its fully at operating temp , after setting the fast idle and choke when cold.

Loyale 2.7 Turbo Posted September 7, 2011 Share Posted September 7, 2011 ...and after awhile of driving, i stop at a light and it idles down to nothing and stalls... Sounds like a Dirty Carb to me... Could I Ask When was the Last time you Took it Out to Deep Cleansing? if you Haven't done that, you Might Try the Carb Cleaner Spray Procedure First, here is a Link to a Basic Tune-up & Carb Cleansing Procedure that Might Help: http://www.ultimatesubaru.org/forum/showpost.php?p=987097&postcount=2 Kind Regards.

I was hunting the other night for some tips and didn't find anything useful. I will give this a try. I am not too worried as I am about 20% on my way to funding a EJ swap. If I wasn't, I would be doing the Weber swap. Link to comment Share on other sites More sharing options...
BratWarrior Posted September 8, 2011 Share Posted September 8, 2011 I'm having the same issue with my EA81 Hitachi. I rebuilt it and it seems to be running smoother. But it still dies at a stop sometimes. GD told me that the choke might not be working properly. So you might want to give that a look see. I'm going to try and replace mine this weekend. I'll let you know if it makes a difference. Link to comment Share on other sites More sharing options...
Moosen Posted September 9, 2011 Share Posted September 9, 2011 Same issue! Is it easy to completely take apart the carb and clean it? Link to comment Share on other sites More sharing options...
Gloyale Posted September 9, 2011 Share Posted September 9, 2011 Take the top off the float bowl. unscrew the brass cap over the slow idle passage. (it's the one inline with the Anti-dieseling solenoid) Under it is the slow idle emulsion tube. Unscrew it. 99% chance there is crud in the bottom of the tube. Blow it out. This should correct idle issue. Good idea to remove all the jets and tubes one by one and blow them out while you're in there. Link to comment Share on other sites More sharing options...
ferox Posted September 10, 2011 Share Posted September 10, 2011 Cleaning carb bits usually yields better performance, but also make sure you change your fuel filter if you haven't done so in a while. Link to comment Share on other sites More sharing options...
83pickle Posted September 11, 2011 Author Share Posted September 11, 2011 I got the engine idling back to normal buy adjusting it more. It sits around 1100 which is okay with me for the time being. Like I mentioned earlier, I will be EJ swapping before too long, so I can be patient. Thanks for the tips. Link to comment Share on other sites More sharing options...
BratWarrior Posted September 11, 2011 Share Posted September 11, 2011 I replaced my choke and that seems to have worked. The speedo needle isn't jumping and it's idling lower. Give that a shot if you become impatient. Link to comment Share on other sites More sharing options...
