My Ariens riding mower motor is popping while running; it sounds like popcorn popping! It has fresh gas, a new fuel filter, etc. Several times I used carb. starter spray.

Hi,
Could it be the spark plug gap length? Shutting off the motor, without letting the mower idle a bit, could cause this.
Also a damaged spark plug will cause backfire, and a carburetor which needs adjustment will also cause afterfire.
I am including a link to Ariens support:
Have a blessed day!

You were right! I removed old spark & cleaned it; runs great! (Did replace w/ a new plug yesterday.) Thank you, Robyn!
You could have a damaged spark plug.
