916H creeps backward

Recommended Posts


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.

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)

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁

      It's in pretty sad shape, but yes I have a yellow plastic cap that I'm fairly certain is what you need. PM me your details and I'll get it out to you.
