when the engine is cold and start it the idle rises to
2000 RPM and drops to 1000 RPM after is warmed and stays in same position all the time.
I have cleaned the intake valvs with gum cleaner and
tried to adjust the air intake by closing and opening the air mixtur bolt but still have the same problem.
please advice me what to do.?
