    Carb advice - dies with choke off

    I'm far from a carb expert so I'm hoping to get some advice. I'm fixing up a riding mower that runs fine only with the choke engaged. As I disengage, it gets a surging idle and then dies once it's almost fully disengaged. Does the carb just need a good cleaning or should I be looking at something more specific? Thanks. Unrelated, so far I've changed the plug and cleaned the air filter.

    It's running lean, carb is plugged up or the fuel pump/filter is dying

    Ok thanks guys, I'll pull the carb off and clean it out really well. Anything I should be extra careful with, that might break, while I'm taking it apart?

    X2, on cleaning cause you know what hot temps, lean condition and possible bad gas will do to an engine.

    I took the carb apart and cleaned everything. It took Cale coming over to tune it for it to run properly. Thanks everyone for the advice and Cale for his mad tuning skills, much appreciated!
