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. Seem to have a good fuel supply, 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 and the plug on that cylinder was fouled badly prior to changing the plugs as if that cylinder has not been firing for some time. Bought at an auction so no history at all. Has me scratching my head, any ideas would be greatly appreciated.
