Hello
Yfm200N having issues to keep it running this what I've done so far. New petcock, new air filter, new coil, new plug gapped correct, adjusted intake according to service manual , removed carb cleaned out all wholes in the main jet ( did not rebuild). Ran it without gas cap, ran it without carburetor breather tube same problem. Starts up runs when cold for a bit longer then dies. Re start it seems to die faster. Sometimes is it's like you turn the key off. Other times it starts to stumbles. Have not adjusted float at this point any help will keep would be great before I burn this machine to the ground lol.
