I HAVE A SELFPROPELLED TROY BILT 160cc honda engine. I have replaced the air filter ,spark plug,gas,and carborator. It appears that I'm not getting any spark . IS THERE A MODULE THAT CONTROLS THE SPARK UNDER THE PULL CRANK...

Hi,
There is most certainly an armature/module/coil that the magnets of the flywheel swing past as the engine spins to produce the spark. Yes, it is beneath the starter and blower housing; best to remove both at one time, usually. There will also be a wire that connects to the shutoff swich that will be attached to the throttle/governor system; follow the calbe from the safety bail.
Peace,
Clarke
