Excellent Replacement Engine
By Tom W. 
Tyler, Texas
Purchased 05/27/2020 | 
Review Posted 07/10/2020 
This 11.5 HP B&S replaced my original 12.5 HP B&S on my 30" Snapper rider and even with less HP it mows better, starts easier, and is quieter running.

It has a fuel shutoff solenoid that prevents carb float valve seepage that was a routine problem on the older engines.

Briggs & Stratton Is A Great Engine!
By Rob B. 
Byron Center, Michigan
Purchased 01/08/2020 | 
Review Posted 01/31/2020 
The original shipping estimate stated five to seven business days, and we received the engine in two days. Installation went well, and this motor runs great and has plenty of power. I would definitely recommend this Briggs & Stratton engine and supplier to anyone in the market for a new engine.
