Wrenchin, Glen and I'll add Franklin Marine to the mix.
Who ever you have do it, insist on a leak down test to be done to the engine. A engine can have good compression and still have mechanical issues. Most places rely solely on compression test to check the health. I have one here now that belongs to a fellow CFF'er and he paid someone to look at it and they performed a compression test and said that the idle issues and low speed issues it was exhibiting was from bad gas, so he bought it. I now have it here being torn down because all cylinders failed a leakage test and #1 has 72% leakage. So his issues are mechanical. I need to post a page out of a factory manual stating that IF a engine that has even compression but is hard to start and performs poorly should be checked for scorn cylinder walls, bad ring, worn rings, ect. In other words you can have good compression and issues. Of course, these are just MY opinions and practices. emoToast
I have attached the scanned page outof the manual. This is out of a Factory OMC (Johnson/Evinrude) manual but applies to any engine.See attachments below.

Ditchdoc's was a Mercury that we found that had high leakage on Cylinder #1. I perform mine at 1/2" to 3/4" ATDC. The carbon that builds up at the top of the cylinder will give a false reading. Like on Ditchdoc's, #1 had 70% at 3/4" but had 6% at TDC. The other 5 had 6% at 3/4". If a cylinder is good, it will be good all the way down to the port or idle relief. Again, my opinions and practices. emoToast </p>
