kenDAWG Posted February 5, 2013 Share Posted February 5, 2013 Have you messed on with the float level?? Sounds like you're carb is over flowing do to the float pin (can't remember its real name) its got the rubber tip hasn't closed due to the float not pushing it up!! Check make sure float isn't jammed up and there isn't anything stopping the rubber tip pin from closing the inlet hole!! There is prob a better way of explaining this but I'm on my phone and off to kip Cheers Ken Link to comment Share on other sites More sharing options...
slice Posted February 6, 2013 Share Posted February 6, 2013 Kens right, your float is either stuck down or the needle valve is not seating properly, give the float bowl a sharp tap with the end of a screwdriver that sometimes works just to knock it back into line.

shambles1980 Posted February 6, 2013 Share Posted February 6, 2013 just thought id mention it could also be that the overflow screw (little jobby down by the overflow pipe, that you can see with the carb on the bike.) isnt in properly, or the little seal on it isnt on it.. if you undo that screw fuel will come out even if the float is set right and the little pin it upshes up is fine.. but as already mentioned. i would also check that the little pin the float pushes up is actually there. and that the float is pushing it up when its in the up possition.

WherEmEweeD Posted February 6, 2013 Author Share Posted February 6, 2013 Before i remove and take the carb out could it still be that the float pin is stuck down or the needle valve is not seating properly even if i have not had the carb removed and taken apart. I have only really taken the hoses and airfilter housing off and maybe a pipe or two but i made sure to put it all on correctly. was working correctly before i cleaned around it. I will check the overflow screw now. is the overflow screw same as float chamber drain screw? Link to comment Share on other sites More sharing options...

YPVS TONE Posted February 6, 2013 Share Posted February 6, 2013 It sounds like you have a small piece of dirt between the tapered float valve and seat if you didn't take the carb off. Try turning the fuel tap to off, unscrew the float bowl drain screw and drain the float bowl until fuel stops coming out. Do the drain screw back up and turn the fuel tap back on. Sometimes this is enough to flush the dirt from the valve seat. Try it again if it doesn't work first time. Link to comment Share on other sites More sharing options...
WherEmEweeD Posted February 6, 2013 Author Share Posted February 6, 2013 Is the fuel switch the choke? I did like you said and will test her out tomorrow when i get more fuel. Link to comment Share on other sites More sharing options...
blackhat250 Posted February 6, 2013 Share Posted February 6, 2013 If you asking " is the fuel switch the choke" sounds like its a vacume petcock, as you"v never switched it on/off, my bet is youv got pipes mixed up , fuel in vacume inlet , instead of fuel inlet, coz youv not had carb in bits ,for it to f*ck up, Link to comment Share on other sites More sharing options...
WherEmEweeD Posted February 7, 2013 Author Share Posted February 7, 2013 Yeah i think you could be right on it being a vacume petcock I will post a few pics tomorrow as i had a last look at the pipes and tbh i would prob do more wrong messing with them. maybe a small video showing the pipes and where they goto etc. Link to comment Share on other sites More sharing options...
davidjlambert Posted February 7, 2013 Share Posted February 7, 2013 Dear WherEmEweeD Go onto page three of this forum to "xt 125 r petrol leak" which describes similar problems I had. I presume you removed your float bowl and assuming you didn't adjust anything then it must be a problem with the float needle valve not seating properly. Did you remove the float and needle valve? It's a pain to keep taking the carb off but from the link I mentioned you will see a recommendation for testing if the needle jet is seating with the carb in your hand. Will save a lot of time. Best of luck Dave Link to comment Share on other sites More sharing options...
