Starting Issues for a Hustler Mini-Z

[Devan]

I have a question for the Hustler experts here.

I have a Mini-Z 36 that has starting issues.
Starter motor spins over when the ignition is run, but the pinion does move up and engage the flywheel.

I have replaced the battery and solenoid, with no improvement.
I have seen mention of an ignition kit that can boost the output of the solenoid and was wondering if this could be a remedy?
I really don't want to buy a new starter due to cost, but have been down for 4 days now with the delay in getting the solenoid and am running out of time.

Any help is appreciated!

Engine is the 17 HP Kawasaki : # fh54v1 - bs37 - r

eng # fh541va44301

I'm just a little amazed that the starter and or ingnition could go from operational to complete **** down in 7 days due to a dying battery...
