KristjanJohann Posted May 14, 2010 Share Posted May 14, 2010 I have a Leone '86 with the EA82. I have had a problem with the Hitachi carburetor with manual choke. It runs fine but it won't idle. I've tried carb cleaner, alot of it, but it didn't do any good. At one time or another I've had this problem with all of my previous EA82s. Usually this problem goes away in a few miles, but not this time. What is causing this? Quote Link to comment Share on other sites More sharing options...
Frank B Posted May 14, 2010 Share Posted May 14, 2010 Does it have electric solonoids on the carb? One is a fuel shut off that only opens when voltage is applied, I think there's an idle mixture one too? I can't remember. Either way, make sure 12 volts is present, if not, trace the wires to find the problem. I that's not it, you may have to pull the carb, and tear it down to clean it out, the idle circuit could be plugged. Quote Link to comment Share on other sites More sharing options...

idosubaru Posted May 15, 2010 Share Posted May 15, 2010 took one spare hitachi apart once and it ended up in the trashthat's where they belong...well maybe the scrap yard has less of a carbon footprint? you're likely going to need to revisit cleaning a carb or possibly rebuilding it. seems obvious you need to focus on whatever regulates the idle.

ellets Posted May 16, 2010 Share Posted May 16, 2010 put a weber 33-36 carb on it. will run better more power and problem solved. I got one from a member with adapter very reasonable. run search for weber carb, there should be some good writeups on conversion. Quote Link to comment Share on other sites More sharing options...
KristjanJohann Posted May 17, 2010 Author Share Posted May 17, 2010 The exchange rate is craaaazy now, we have to pay up to 3-4 times more for the same part if we import it here So a webber would be maybe $200 for you, but for us we would need to pay $7-$800 Quote Link to comment Share on other sites More sharing options...
Markus56 Posted May 17, 2010 Share Posted May 17, 2010 turn up the idle and see if it still happens. Same thing used to happen on my 85 wagon. Quote Link to comment Share on other sites More sharing options...
oskar_subaru Posted May 17, 2010 Share Posted May 17, 2010 turn up the idle and see if it still happens. Same thing used to happen on my 85 wagon. tried that, but only thing it changes is that WHEN it decides to idle it does it at 1100rpm instead of the usual 750-800 Quote Link to comment Share on other sites More sharing options...
Markus56 Posted May 17, 2010 Share Posted May 17, 2010 might be something as simple at the carb to manifold gasket. have you sprayed it with brake cleaner or something to detect a vacuum leak? Quote Link to comment Share on other sites More sharing options...

robm Posted May 18, 2010 Share Posted May 18, 2010 That problem really sounds like a flaky connection on the idle solenoid. Does it have one on your model? Or was that a North America only item? It could be crap in the float bowl, perhaps. If it has no solenoid, then try cleaning the float bowl. It is a lot less work than tearing into the whole carb.

HILLBILLYHARLOT Posted May 20, 2010 Share Posted May 20, 2010 OK, I just rebuilt my Hitachi on my EA82. It's really not bad. I took everything out and cleaned it, one thing at a time. Take 1 jet out at a time, clean it, spray carb cleaner through the holes, and when you replace the accelerator pump, DONT forget to put the little ball bearing (check valve) in!!!! I also replaced the O rings on the venturis, (sounds scary but really not) and I took out what I think was the idle solenoid, it was full of corrosion, cleaned, let dry and put back in carb. It runs like a whole new car! I also shortened my throttle return spring, it wasn't tight enough and would idle up when I took my foot off the throttle, or pushed in the clutch. I'd be happy to walk you through a rebuild, I think it will fix your issues...Oh, I also had a bad base gasket... Quote Link to comment Share on other sites More sharing options...
