Yanmar Compression Tester

When diagnosing my Yanmar generator issue, I had the need to check the compression on the engine. So I built a compression tester using an old injector. 

Here are pics. 

If you ever need to borrow it, let me know.

Nice addition to the service tool collection.  Good for checking carbon loaded valve seats!
