Question about Briggs AND Stratton Intek Briggs & Stratton Vertical Engine 21 HP INTEK OHV 1 x 3-5/32 331877-3036 331977-0001
Reg battery wont turn over after hitting compression stroke. put on charger and will start. New 410cca battery. Is there a compression relief valve? If so how to fix. I am old school mec and not up on newer stuff.
If its the 21 or 20 hp OHV single briggs. Adjust vales to .004. The cam also has a decompression that breaks, Causing hard start. So if valves are adjusted and u still have problem. "Could" be cam, remove bottom cover and inspect cam. new cam about 75 to 100 bucks.

Most Briggs deco vaves are internal and pretty reliable, the valve clearances are very important, if the exhaust valve clerance is too wide the valve lifter will not work, if there is no adjustment yoy would have to fit a new service valve and re do the clerance by removing material from the valve stem
