ok I was about to go put up flyers around the neighborhood for grasscutting and figured i would start the mower first and see if it still ran fine BUT it wont turn over now any suggestions i already looked at the spark plug and it has plenty of spark.

 

it wont turn over or wont start

 

take the plug out and try to pull start it with no plug

 

check the side cover to see if you dropped a valve or remove the engine from the mowing deck and pop open the sump cover and rotate the crank by hand and see if there are any restrictions.
