B&S does not specify compression readings. Look for 120, give or take 20. More important than actual compression is the difference between the 2 cylinders.
any where from 120 lbs to 180 lbs
Any thing above 130 lbs
90 to 120 minimum in 3 to 5 revolutions of the motor
Briggs doesn't publish engine compression specs, but 120 is good. 100 is okay. 80 is lousy.
briggs doesn't offer compression ratings for their engines. I will usually pull it 3 to 5 times and look for 90 to 120. anything less is a problem and if it doesn't hold compression there is a problem
I just got 110 - with new rings but still doesn't run right. ...
Try 32 thousands, to start, depends on how much compression the engine has at this point.
Leak down test : Uses 70lbs pressure to test for leaks around valves and cylinders.
