Engine Surging and will not hold steady idle

Mechanic's Assistant: Can you guesstimate how old the engine is? And has it done anything like this in the past?

Has not done this in the past, age I believe to be 2014

Mechanic's Assistant: Do you plan on doing the work yourself?

Yes, I am a small engine mechanic but this one is stumping me.

Engine make and model? Single cylinder? Usually, it is a lack of fuel that causes the surging. Check tank line, and all the hoses and filter up to the fuel pump inlet.
