Yardman Noises

Mowed the lawn today 9/27/14 and am getting some wierd noises from it. At high rpms doesn't sound too bad but at half throttle to low makes a noise like "CLUNG, CLUNG, CLUNG.' Rpms go up and down between clungs. I know it means engine work but where to look first? Can't be the crankshaft because two pulleys come off the shaft. Any ideas? Valves? Pushrods? 13.5 Briggs. Fall/Winter project.

Makes the noise without the mower deck engaged.
