Briggs & Stratton 33S877-0019-G1 Vertical Engine with Electric Start.
This motor was purchased as a replacement for my Craftsman Lawn Tractor. I found the B&S model on the Equipatron web. I contacted them as I had some questions about installation. Customer service was super friendly and NOT in any hurry to get me off the phone! They answered all my questions, some of which needed the person to contact a more technical type.
I installed the motor in my machine. Installation went very smooth You do have to have some base mechanical knowledge to get the job done. There should be a install note to remove that screw that stops the throttle from hitting the choke mechanism.
Electrically it was super easy, plug and play!
Overall, working with Equipatron was great, and the product is 5 stars!!
