Looking for input from the MB think tank - Idle Issue
Posted: Sun May 12, 2019 9:43 pm
I have a 2008 125 with 6,500 miles. Scooter is in decent shape. Runs great once it is running, but won't idle after it has been turned off and sits. Idles fine once it has been warmed up. Carb has been thoroughly cleaned. Auto enrichener has been tested and is reading as it should. I have also swapped it with another one just to be sure. I don't think it is a temperature issue as much as a sitting issue. Petcock has been tested and doesn't flow without suction. Fuel system has been flushed, and fuel filter replaced. I sprayed ether around the carb and intake, no vacuum leaks present. I have replaced the coil, plug wire and cap. I have adjusted the valves. The intake valve was a bit tight. I've replaced the stator and CDI. I have cleaned the float needle seat, replaced the needle valve and set the float to 18mm. I am out of ideas. It is running the same as before I began working on it. WHAT AM I MISSING?
