Hi, My name is***** you for letting me try and assist you with your problem.
This happens when the valves wear into the seats or a valve gets bent.
You have to adjust them to make up for the wear.
If you know what the engine is I can look up the specs for you so you can check it with a feeler gauge.
On some of the old 5hp briggs engines you have to file the ends of the valve stems down to get the clearance big enough to get them to run.

Alright.
Did you happen to watch them move as the engine turned over to see if they all moved according to the cam movement?
If they do the only possibility left is a stripped cam gear.
They are plastic gears.
