    Loose or faulty connections or ground or perhaps a weak or dirty shaft on the carburetor Solenoid maybe?

    Defective ignition switch?
    Put a test light from + on the coil to the block and watch it for a minute.

    PLEASE edit your post and put the actual subject in the subject line.

    How many hours on engine and how well maintained has it been? Bad gas can affect carb. Poor lubrication from infrequent oil changes can affect valvetrain.

    How often was machine used?

    Check your low idle rpm, could be too low, which causes issues

    Confused

    I have a miller bobcat 250NT serial LE16428 with the Kohler CH20S motor in it. Every now and then when I start it it will run rough when I switch it to auto idle. It seems to run fine when on high though. When it is running rough and I go to shut the switch off it idles to high and won’t kill the motor. But If I shut the gas off and let it kill itself then restart it it will usually go back to smooth idle and the ignition switch will work as it should. Any ideas?
