If it is a running rebuilder, I would venture to say around $150 to $300,maybe a little more if it runs really well.
.
If it has a starter on it, you can get the oil system primed and then crank the engine over to get a compression reading.That can tell you a lot even though it will be a cold test as compared to a warmed up running test.


There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.
