Kawasaki won't start.

I have a Cub Cadet with a Kawasaki FH661V motor. When i try to start it . All it does is trun over real slow then stop. But if i hook up a jumper to it. Then it spends real fast and start. I have put a new solenoid and Battery. Tested the starter is good. Then I justed the valves. Still wont start. Aim I missing something to check out?

How exactly are you jumping it, with the mower battery or a vehicle battery?

If you use jumper cables from mower battery to starter, any change? You said you adjusted the valves, what did you set them at? I like to set them then manually turn engine a few times then recheck.

Could valve clearance cause hard starting? A shop also told me that starter can cause hard starting?

Yes it could. Also a failed ACR on the camshaft, Bad starter bushings, or even a poor electrical connection.
 
On the ACR failure this can be checked for without going deep inside the engine by checking the ACR bump on the rockers. As you spin the engine up to TDC compression stroke of each cylinder their will one rocker that opens slightly and then close again. IF this doesn't happen the starter is force to try to crank against the engine's full compression which the starter is too weak to do so.
 
IF the ACR bump is present and valves are adjusted properly then it can be either the starter or electrical connection problem.

Cub Cadet (MTD) only sells the complete wiring harness. Lists for 166.40 that's why my shop makes up the needed wiring from individual components as required. This requires the equipment to be in my shop however as an hydraulic crimper is required for the larger cable terminals and heat shrink insulation.

As for battery to ground cable is NLA from OEM and has to made in house.
