Working on a MF 165, Perkins gas engine, starts up fine and after about a minute it starts fluttering, when I pull off the number 2 plug wire it seems not to change anything. Have rebuilt one carb and switched out to another, changed the points, cap, rotor, and plugs and moved plugs and the wires and it doesn't move the problem. Today pulled valve cover and checked the rocker arms and valve train all seems fine, compression on that cylinder is down about 8-10 psi from the other 3 cylinders. Has me scratching my head, any ideas would be greatly appreciated.
