Professional cylinder head rebuild.190e... Leaving fluffy black deposits on all plugs and in exhaust. Since reassembly, I have double checked compression. Cold compression test 1/130, 2/130, 3/140 (new exhaust valve here), 4/125. I have also double checked crank to cam timing... Both top dead center marks correspond to distributor position and compression stroke and firing order. I have also replaced the fuel pressure regulator. But she is still running rich and rough. What could the matter be?
