My daughters mini bike with a 3hp Briggs has 80psi compression and runs great. A motor I got "running" off eBay has 55psi compression, runs but has NO power.

It should have a minimum of 70 psi.
120 is nominal
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
Briggs doesn't publish engine compression specs, but 120 is good. 100 is okay. 80 is lousy.
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
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.
14:1 compression
120psi
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.
