When I shut off the engine ( 17.5 Hp Troy Bilt mower) it of course spins a bit until it comes to a compression stroke then stops. Go to try to start again and it will not go through that compression stroke acting as if the battery was low or starter is weak. If I spin the engine back a bit so that it has a running start coming to the compression stroke it will get passed it and start. New battery and starter. Any ideas?

Save the old starter. Could be good. Take a jump pack and see if the starter spins over.New battery and starter.
Agree check valve lash as ILENGINE said.

Number one problem is the valve lash adjustment.
Go to a You Tube site called Teryl fixes all. He is a bit of a clown but has all the info you need about how to adjust the valves.
The next problem could be more serious and the compression relief mechanism is broken or stuck on the camshaft. This would take professional repair knowledge to correct.
