Hello....and Help

Good day all. I'm 40 years removed from my high school small engine class, Lol. My wife was using our Honda powered self propelled walk behind and and hit a boulder. Mower shut down instantly, blade was bent beyond repair. Changed out blade and mower for all intents and purposes doesn't start...if you're lucky for every hundred pulls you may get a pop. With the wealth of knowledge out here I'm sure someone can point me to the culprit part/s. It was a fine running great lawn mower.

Thank You
Jeff
