That's my story, hope you guys do well with yours.
I'm off to buy an OS.
Good luck with that OS on RB fuel!!! I fear the same result will occur.
Run it on Runner Time (as you should have the Mito) and you'll get much better results.
Just to compare my Mito is at about 5hrs on Runner Time and still has that lovely nip at TDC when the engine is cold.
BTW you didn't say what the engine was doing when running? When are you 'feeling' the compression when the engine is cold or when at operating temperature (or close to it?)
