Adjusting valves on 280000 and 310000 series briggs & stratton engines
I have two riding lawn mowers I decided to purchase to start re-learning small engine repair on. One has a 287707 14.5HP and the other has a 31H777 18HP Briggs and Stratton engine. Both are OHV Single Cylinder Series; 280000 and 310000 respectively.
First things first, I figure I’ll verify easy to reach parts that usually need inspection and adjusting.
Currently, I’m focused on the OHV Covers underside, i.e. inspecting all the parts and setting valve intake and exhaust rocker arm clearance.
This document shows the gap clearance requirements for the intake and exhaust valve’s with their rocker arm. http://www4.briggsandstratton.com/miscpd...
However, I haven’t found a repair manual for each engine series yet since the holidays and am therefore not sure what the torque specifications are for the adjustment stud, adjustment nut and adjustment lock screw.
Does anyone know what the repair or other manual for each engine series specifications are and maybe any recommended advice regarding torque specs?
