Sounds a little low to me. Check to see if all cylinders measure about the same. ANOTHER ANSWER That would be good for most engines. What you're looking for is any kind of serious fluctuation in the pressure between cylinders. If you're getting 90 psi consistently, you're in good shape.

How much compression is good on a briggs and stratton 22 hp engine?
For a Briggs and Stratton 22 hp engine, good compression generally ranges between 90 to 120 psi. Values below this range may indicate wear or damage, while readings significantly above this range could suggest issues such as carbon buildup or valve problems. It's important to check both cylinders for consistency, as significant discrepancies may point to underlying issues. Regular maintenance can help maintain optimal compression levels.

What is the compression in a mercury outboard?
The compression in a mercury outboard refers to the pressure created within the engine's cylinders during the compression stroke, which is crucial for efficient combustion. Typically measured in pounds per square inch (psi), optimal compression ratios can vary depending on the specific model and type of engine. Generally, a healthy compression range for most outboards is between 90 to 150 psi. Low compression can indicate issues such as worn piston rings or valve problems, affecting engine performance.
What is compression on 1975 70 hp evinrude outboard?
Compression on a 1975 70 hp Evinrude outboard refers to the pressure generated within the engine's cylinders during the compression stroke, which is crucial for efficient combustion. Typically, compression readings for this model should be between 90 to 120 psi. Low compression can indicate issues such as worn piston rings, damaged cylinder walls, or valve problems, which can affect engine performance and reliability. Regular compression testing is essential for maintaining the health of the outboard motor.
How much compression is good on a Tecumseh 10hp?
For a Tecumseh 10hp engine, good compression typically ranges from 90 to 120 psi. If the compression falls below 90 psi, it may indicate wear or damage, while values significantly above 120 psi could suggest issues such as carbon buildup. Regular maintenance and checks can help ensure optimal performance and longevity of the engine.
What makes a 90 GEO Storm GSI dual overhead cam fire on only 2 cylinders after I have replaced coil coil and plug wires distributor cap and rotor and set timing?
low compression on 2 cyclenders ALT ANSWER: You have two cylinders swaped on the cap. I did it to mine. Try swaping 1 & 3.
What is the proper compression for a Chevy 283 motor?
It should have 150 PSI per cylinder. If it has a reading of 90 LBS. are less on any given cylinder, Then the engine will idle rough at an idle. / engine miss.You can't have anymore then 15 LBS. difference in any one cylinder.150 LBS per cylinder is a good reading on a fresh are good running engine that's in good shape.You may have only 120,130,140 or 150 LBS. That is your highest reading, And engine will run fine as long as there is no more then a 15 LB. difference in any given cylinder.Hope this answers your question. A 100 or less LBS means the engine is tired / Worn out needs rebuilt.
How much should a 90 pound kid be able to jerk lift?
If your 90 pounds you should be benching 90 pounds, you should be able to bench your own weight An age is typically useful, but 90 lbs. should be the goal (bench your own weight). My cousin is 12 (turning 13 next month) and he weighs 90 lbs, but bench presses 120. I'd say he is very strong for his age and weight but, yeah I'd say 90 lbs. is a good goal to reach.
