hi dear all

 

i am from sri lanka and currently building a KE25. it was badly corroded and now things are getting into shape.

 

finally it is running but plaged with an idel issue. The carb was rebuilt still the idel issue is there.

 

i am unable to get a decent idel as it keep stalling

 

any help is greatly appreciated

Either lean or rich.. What does it run like when accelerating, cruising and slowing down??

 

Lean from still having dirt stuck in the idle circuit, so although the jet might be clean there might still be something blocking a drilling passageway, or lean from having an air leak into the inlet manifold.

 

Rich from having dirt in the needle & seat that has been pumped there after the carb rebuild, or from having the wrong float level, which is hard to do. Either would flood the car at idle.

Thank you very much for the quick reply.

 

Car start up only when the gas peddle is pressed.

 

Will clean the carb again and planning to change the jets

 

. Any directions to do that correctly is much welcome.

Wouldn't bother changing the jets. The problem likely lies in the passage ways inside. After you dismantle everything, make sure you blow through all of these with compressed air, even a few forceful efforts from a bicycle pump then a good washout. Be very gentle if using tools as the brass components are easily damaged. Don't stick any wire anywhere trying to clear imaginary blockages.

well, hang on , back to the basics, we have no idea what your technical knowledge is.

Are you familiar with the idle speed and idle mixture screws?

If so, are you adamant that they are set where they should be?

Take the carby off , look up the bottom of it, and check that the base idle speed screw is set such that the throttle plate is literally resting just about touching the transfer slot hole in the side of the well.

You can recognise the transfer slot by finding the idle mixture screw port and finding the little elliptical port just above that. (above as if the carby were installed in the upright position)

Then when you are sure there is an idle issue, we can assist.
