Lawnboy 20 inch push mower

Lawnboy 20 inch push mower with the kohler 6.75 motor . Unit is being sold as is non running . It was working last yr when last used . Attempted to use it but a no start . I have flushed the fuel system , cleaned the carb ,replaced the air filter , replaced the cracked fuel line and tested the plug . I have gone over it again and found the pilot jet is still plugged from the old gas . I have given up ! A replacement carb is under $30 but no longer wish to put more time into it . If you hv time to re clean the carb and get the pilot jet cleared it’s a good mower .
