Husqvarna will not start but will crank sometime

[afbryant1964]

Hi again everyone, I have a Husky model GTH2554XP with 766 hrs. It has a Kawasaki 25hp engine (FH721V). It will only click while trying to start but if I turn the flywheel by hand until it has no resistance, it will crank but still will not start.
I have changed the known good battery with my other mower with no change. I have taken the starter off and bench tested and the starter moter and solenoid checks ok. The starter is only a couple years old. I don't know if I have one problen or two. When I do get it to turn over, it will crank and crank but never will start. I have set the valve clearances although they werent that far off to begin with.
Any guidance would be appreciated. I don't know what to try next. I have done some research and have read maybe it could be the pinion gear on starter but I probably would have noticed this when I had it off,or maybe decompression release on cam? What should be my next step? Maybe I have missed something simple.

Locate the main fuse, pull it a reseat it a couple of times so it makes good contact. The pins typically corrode and create resistance.

Let me know if that helps. If not, you need a multimeter to test further and more accurately.
