If it's an ohv 31xxxxor 33xxxx that is opposite of how it is supposed to work.On my old tractor with a 17 hp Briggs I used to have to set the valves once a year otherwise it would build compression and not even turn over. Their tricky devils to set valve lash on.
I ended up setting it on the loose side and it’s been good for a year and a half so far.
Bad idea.I adjusted them on the looser side of the specs. If the called for say 3-7 thousandth I went on the 7 side.
Good point... The last Briggs Vtwin I adjusted, the manual showed to set it just a bit off TDC on the cyl.. I don't remember the deg... but it was in the book.Don't forget most OHV engines have a compression release that works at 300 rpm or less to make the engine easier to start. When you adjust the valves you need to turn the engine past top dead center. I usually like to see the piston move about a 1/4" down the cylinder so I'm fairly certain the valve is fully closed or seated.
Also invest in a torque wrench, you don't want to guess at the tightness of the locknut or you may snap off the valve adjuster stud. It's easy to think you have it tight enough when you don't and then next time when you think you didn't tighten enough really twist it and snap it off.
All Briggs v twins and pretty much all Briggs overhead valve engines at least all that I have ever seen or know of set the valves at a quarter inch past top dead center on the compression stroke.Good point...
