My engine is a Briggs & Stratton / Intek #33R877. If you need a head gasket kit I picked mine up on Amazon - but they have or won't give out any specs on engine,, briggs & Stratton goes by completely diff # system , so I am going to have to go by cyl bore and crank size 1.497" only 3 engines have that crank size but each have a diff cyl bore , didn't have time to measure the bore yet but the torque specs are 150 -175 inch lbs depending on cyl bore. The original specs for the build called for the DM700D which was rated at 19.5 hp. The only thing done to the engine was the rpm's were limited by the governor. If I remember that is where the 23hp came in. It's not so much the horsepower as it is the torque with these engines and the most torque was usually in the middle of the curve. 7:00 am–9:00 pm.
