My 900 cfm 4150 has 78 jets and 73/63 power valve restrictors. I think its pretty rich on C16 with my little 460 BBC on 20 psi.

What jets and PV restrictors are you guys running with your combos?

Thanks,

Mario

I wont go here with jet recommendations, Got to read that plug, but your main jet sounds normal.
Steve, I'd pay money in a heartbeat if you made a video of how to read plugs!!

He has a video on that, but I'm always second guessing my ability to discern oil spotting from detonation. Of course, maybe I'm just not bright :)
