Hi Gary;
Let's see. How to answer.
The engine has been signed off for a top overhaul and a bottom overhaul within the last 300 hours,

If everything was done correctly you have an engine that's 300 TSMOH, and should run well for years to come.

I would still ask for a compression check, and if a local mechanic has a borescope, ask him to "scope" the cylinders. He/she will need to check the appearance of the exhaust valve to see if there's any evidence of burning or high heat along an edge, and to see if the cross hatch pattern is visible in the cylinder walls.

Let me know how it comes out.

Best,
Steve

Looking at a Cessna 150

The engine has 1600 SMOH
300 Since a TOP Overhaul
200 Since a Bottom Overhaul

I'd be interested in views on the SMOH vs TOP vs BOTTOM

thanks
