Hi. An incorrect clearance of the valve (in particular the intake one) and/or much carbon deposits inside the valve adjusting room...can cause the problem that the engine does not keep the idle even if the bolt of regulation of the idle is in the position of maximum ? I have this problem with a 2004 Kymco KXR 250 sport: the carburetor is perfectly clean, there are no places where air can enter supply circuit, the spark plug is new, air filter well cleaned and so on. The carburetion setting is a little bit rich...but i don't think that is the problem. I have seen that the spark plug becomes dirty with carbon deposits very quickly. Thank you very much in advance.
What was the 0.00 supposed to be? 0.10? Same as bottom one?
