Cub Cadet rzt 22 starting problem

[Mas1959]

I posted this in the engine repair area and thought it might be better here.

Need some help here. Mower is intermittently not starting. Would click when you turned the key. Turn it again and it may click or turn over. it was the original battery so I replaced it. No difference. Replaced solenoid and now the starter. No change. If you keep turning the key it may click or turn over or just turn a little bit. switches apparently are fine as it is turning over. But it seems to be turning slow. Many times the starter does not retract. It will do this even when crossing the solenoid terminals. When the key is turned to start the voltage will drop to 5 or 6 if it doesn't turn over and 8 or 9 if it does. Voltage is fine at the third wire on the solenoid. Any suggestions?

If the electrics check out OK.
Check the decompresson is working.
If the valve clearence is excessive the valve can not decompress at cranking speeds and those small starters can not overcome full compression.
