120 is nominal
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
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
I just got 110 - with new rings but still doesn't run right. ...
An engine requires gas and spark to fire but it also requires compression and timing. If it has gas and spark, I would check the compression...should be over 100 to run good. If it has good compression then I would check to see if the spark occurs when the compression does. If it doesn't then you probably have a sheared key on the flywheel.
Leak down test : Uses 70lbs pressure to test for leaks around valves and cylinders.
A good quality 30wt is Briggs recommendation
Compression testing is done on engines and it establishes whether the engine has good compression. Good compression is needed for the engine to start easily and run efficiently.
that is not a good model number for briggs. also you need the type.
No, it is good in tension.
