Donnie ... What spark plugs are you using in your 2.3-16? I think that it might be wise to use a colder plug than the stock plug.

The engine is now broken in and I just finished a compression test. I read 175 psi in each cylinder. That is very close to the compression with standard pistons and I was expecting to drop the compression ratio by about a point. I had guessed that the compression should have been about 160 psi since I had shaved 1.5 mm from the piston crown.

Any thoughts?
