Cyl Compression

[tkent02]

One more thing, Utah is mostly high elevation, don't know where you are at but I bet it's up there.
There will be a lot lower reading on the compression gauge at these elevations, there's just less air available to compress in the cylinders.
Same reason a perfectly running engine will be a lot less powerful in the mountains than it is down low.
What's important is that the cylinders are all in the same ballpark, none way higher or lower than the rest.
Thanks for the reminder, I have to send a few shims back to him.

You're right. Valley floor averages 4500 ft. All cylinders were checked properly (hot) and were a consistent 115 psi.
