916H creeps backward

[bosmatj 0]

Our local small engine guy built a working Kohler 16 out of the 3 dead ones we had, and repowered our AC 916H. The strange thing now is that when idling in neutral, the tractor creeps backward. It does that with such force that it will walk over a 4" brick set behind the wheel. Any ideas on why it happens and how to fix it? And, yes, the neutral setting is right between the arrows on the rear shifter plate.

Thanks!

Here you go. Download the Simplicity version from their website. Only difference is Briggs engine instead of Kohler.

Did some more searching. Here is a link to the AC owners manual

Here is a link to the parts list. (Simplicity though)

Made the adjustments as directed. Now she stays in one place while idling in N.

Thanks,
