SOURCE: what is the valve clearance on a briggs &
.003-.005 intake, .005-.007 exhaust for single cylinder OHV
SOURCE: hard to start 18 hp briggs &stratton
cold engine
loose .002 exhaust
loose .004 intake
be sure both valves are closed and you are on top dead center TDC of the compression stroke when setting
SOURCE: how do you adjust the valves on a 17.5 ohv briggs
Hi 1st remove the rocker cover and spark plug
hold a long skinny screwdriver down the plug hole and wind the engine by hand until you get top dead centre (NOTE WATCH ROCKERS) first the intake valve will open then close when it closes the piston should be coming up to top dead centre and both valves should be closed and the rocker loose setting should be 0.004 thou you need to undo the locking screw down the centre of the adjusting nut then you can adjust to setting, (DONT FORGET TO DO THE LOCKING SCREWS BACK UP) reassemble
SOURCE: timing for briggs and stratton 15.5 engine
There are no timing marks, timing is correct when the flywheel key is in place, the flywheel is properly torqued and the air gap for the magneto is properly set
SOURCE: i have a 17hp briggs and stratton vertical intek
adjustment with 4000 feeler gauge
adjust top valve when the bottom valve is fully compressed and than with the top valve fully compressed adjust the bottom valve the same way.
very easy But remember to losen the center tork screw before adjusting the rocker arm nut
