problem
 

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 :humm:

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.
