I would greatly appreciate some thoughts on my lawn mower problem

i have a Briggs and Stratton quantum engine
it has spark and fresh fuel but to get it started I have to pull and pull the cord to get it to turn over
and when i get it started it runs for a couple of seconds and dies
any one have idea's
 
Check oil level on dipstick & condition of air filter. You need to adjust valves with engine cold so post model xxxxxx, type xxxx, trim xx, & code from engine. What weight oil are you using:?
 
okay... most likely the carb will need cleaned. probably what is is happening is it will run on the choke, and then when the muffler warms up the thermostat opens the choke and it dies due to not enough fuel.
 
I Just took the air filter housing off and the air filter is brand new

and when the throttle cable is in off the first valve is open but when you go to put it in to full power it closes

The throttle in full power close the choke, and the carb is choke on. After the engine runs few seconds you must close the throttle at working RPMs, and the choke open to run.
