I have a Troy Built Horse with a Kohler Courage SV620-3215 22 HP engine that is just now running lean. It starts out fine but after a few minutes, under load, it runs lean. I've cleaned the fuel tank, replaced the fuel filter and cleaned all fuel lines but the problem persists. I'd like to remove the carb, clean that and replace the fuel pump, but I can't remove the carb because the low fuel solenoid hits the frame.
So two questions: 1. What do you think my fuel problem is and 2. how do I remove the carb from the engine short of removing the engine from the frame.
I've had this mower for 3 years and this is the first problem I've encountered.
