twin engine deep vee.one engine running good other is not. All new fuel ,filters,plugs,fuel,motor sounds like it is running on 3 cylinders and excess fuel coming out of prop wash.
put new plugs in ran a little better for a few minutes. All plugs are black and wet.
I did the following: ran engine to get warmed up, check compression was good,plugs all sparking the same and jumping a good 3/8. went to each cylinder while on high idle and they all make a difference.Ran sea foam in tank,cleaned vapor tank
fuel pressure is a constant 37 psi. I had a 200 black max that was pumping fuel into block from a defective fuel pump. Could that happen on this engine.
