valve/push rod question

I have a 17.5 hp overhead valve engine that was not running well. I removed the rocker cover and discovered the push rod on the bottom valve had broken off. I replaced the push rod, but when I turn the motor the top valve moves in and out but there is no movement from the bottom valve. Is this an indication of a stuck valve and if so is there an easy solution? Also, how can I tell if the bottom valve is the intake or the exhaust valve? Thanks for your help!
