I just installed a new battery. The mower cranks when I try to start with brake paddle fully depressed, in neutral, and deck is disengaged. However, it would not start. Gas tank is full. Checked spark plug and it is firing. Cleaned air filter. Could not figure out what is wrong. It has Briggs & Stratton 14.5 OHV I/C Gold Engine.

Carburetor was completed clogged up. Due to old fuel, solenoid valve was stick closed position. I took carburetor apart, cleaned everything, and made sure the fuel is flowing in carburetor chamber, and now it is working like new.
