2007 honda recon 250 wont idle

Recommended Posts

Ok so I have a recon 250 that will not idle. It will rev up and go as long as u don't let it idle it will run fine. Fist thought to everyone I know would be the idle jet. Cleaned the carb and put a kit in it while I was there. Changed the spark plug as well. These carbs have that fuel cut off vacuum valve on it. If I take the line that's coming from the intake and plug it off it will idle just fine with no problem. I know its not how its pos to be but I just cant figure anything out on it. Im at a lost. Any suggestions would be appreciated. O Ive already checked the valves and also adjusted the air. Its got to be something with the vacuum operated valve whatever it is or does... Thanks.

I'm working on a 2001, Recon 250 that wont idle either, it revs fine till you let off the throttle, but it backfires through the carb an exuast, so I'm going to change the cdi box, an then the coil, only reason,,,is because we have another one that runs fine, so ill just try them to find out if it fixes the problem, then if you think yours is doing what I described, this may be a fix for your recon, ill let you know

Because it idles when you plug the vacuum line, it is exactly that - a vacuum leak. Check the valve that the vacuum line plugs in to. It is allowing air to flow directly through it. Probably a bad valve.

      Hello everyone! I recently purchased this quad for a mere 300.00 and it is pretty clean for the year. I bought it from a guy who bought it in a storage unit. He didn’t know anything about it. I got it home and noticed it did not have an ignition coil for the spark plug. I bought the ignition coil, a new battery, new CDI box, new starter relay, new safety neutral relay, new carb and so on... I got it to turn over, but when I pull the plug and check for spark I have nothing.. it has a non factory starter button that works when I push it and turns the engine over no matter if the key or stop switch is on or off..not sure what that’s all about, but it does turn over..just no spark at the plug. Any help would be greatly appreciated! Thanks!

      doesn't idle at times but sometimes when it does as soon as I touch the throttle it just shuts off, what could possibly be the problem? I thank you very much for any help, Thanks.

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law
