rick2752, Your Delco starter is still good. This is the problem we had when we replaced Denso starters on eXmark with Delco. You need to switch some wires around to get it to work right. This happens because eXmark uses a solenoid infront of the starter solenoid. If the solenoid engagement lead on the Delco (permanent magnet) starter is connected with a short lead to the starter battery cable (like it was on the Denso) you will have problems. The voltage generated from the starter motor when you let off the key temporarily energizes the solenoid and keeps it engaged for a short time. Kohler puts an instruction sheet in the new starter boxes to show you how to rewire it. You can get it off www.kohlerplus.com . Look in "Product Catalog" then "Installation Instructions". Put TT-5038 in the search and it will come up as a pdf.
