Gemok Posted January 22, 2017 Share Posted January 22, 2017 It looks like when in my post weird Honda 125 I was overly optimistic when I said it was a runner I went to grab it today and I can't get it to idle properly anymore. Everything said below is with choke on as when it's switched off bike cuts out completely unless the throttle is wide open.At "idle" it slowly builds the revs up till they're at about 6000 I tried adjusting the throttle stop screw but no matter how small an adjustment I made I couldn't balance between it dieing off and racing away. Even when I had it set to slowly die off if I blipped the throttle and the revs hit 3k the revs would pick up and sit at 6k they'd only drop back down again when I undid the throttle stop at least a full turn then naturally they fall off completely and the engine will cut out.I've had the carb off the bike stripped it and cleaned it out today but that has not seemed to help. I've tried playing with the pilot screw which is a prick to adjust on the bike had to make a "tool" out of a paper clip . I suspect the person who's garage it's in has been mucking around with something but I can't figure out how to put it right . The throttle doesn't feel like its sticking anywhere eitherLooks like I might have to pay for someone to have a look at it. Unless someone has any bright ideas?

Guest Posted January 22, 2017 Share Posted January 22, 2017 Everything said below is with choke on as when it's switched off bike cuts out completely unless the throttle is wide open. Are you sure you're using the choke lever the right way round? On a normal CG the choke is off when the lever is all the way down. With full choke you require quite a bit of throttle to keep it running or it will cut out as there's no mechanism to raise the idle when the choke is on.

TimR Posted January 22, 2017 Share Posted January 22, 2017 Do you A Have fuel in it B have the tap turned on and sufficient fuel level to feed the on setting C Turned it to reserve if the fuel level is low enough to require it Quote Link to comment Share on other sites More sharing options...
Gemok Posted January 22, 2017 Author Share Posted January 22, 2017 A) Yes filled the tankB) Yes onC) N/AIt would happily sit and run at 6000 revs without me touching the throttle for as long as I'd let it with choke on or half way. Quote Link to comment Share on other sites More sharing options...
