Tip & How-To about Mtd Garden


On briggs or any motor that has over head valves ..if your having hard start hesitation or just seems like the batterys dieing or it seems the starter just won't turn the motor over .. these motors are high compression, there's a compression release on the cam, the fix is replace the cam and lifters that's it.. but would still have starter and battery tested to rule them out..

adjusting valve on a briggs 446677 _e1.__24hp.harde starting

valve clearance should be .010 " inlet hot and .012 exhaust hot
that is .254mm and .304 mm
valve clearance has nothing to do with hard turning over of the engine
if it turns by hand then fix the starter motor , battery leads or battery
the biggest problem with B&S motors is the valve stems which from new tend to stretch reducing the valve clearance when hot thereby making hot starts difficult if not impossible until the motor cooled down

just replaced head gasket, now has to much compression and won`t wind over fast enough to start. have had starter checked and seems ok .10.5 hp briggs and stratton motor in a murray 32 inch ride on lawn mower

A head gasket will not greatly increase the compression in a a Briggs motor.

My question is Why did it need a head gasket to begin with?
Will bet it was not running...

A more likely cause if not a fuel problem is to check engine oil if that is good remove the wire from the low oil sensor and see it it will start up for you.

Bent push rods are a function of the valve guide coming loose in the head. The valve binds and you end up with a bent pushrod. Fix: Replace head. $94.00
