This is a fresh rebuild. Still in break in for 1 more hr. Compression reads 95-100psi all. (Double oil)

Am I looking at rich or lean or good? This is with the stock 72d jets( except for #2 which has 73d). Thank you

You are still in break in mode using double oil so what you are seeing is not relevant. Until you are running the proper amount of oil and are putting enough load on the engine to creat heat looking at the pistons mean nothing. I would imagine that the plugs are wet and dark?
