Pump hydraulic head is 4, 7.0 mm plunger size, about the same rate as 2 10 mm. Advance is 4 degrees pump, 8 degrees engine. If advance is coming in too late, it will smoke more. Try this, there are 2 springs under the 15/16 cap that has a 5/16 screw in it on the advance block, remove the inside spring and replace cap. Work tractor to see if that helps smoke level any. If not, I would remove all injectors and popcheck to see if all holes are open. Most Perkins injectors have 4 hole tips, if 1 hole is plugged on 1 or more injector power will go down and smoke will go up as incomplete combustion will occur since too much fuel through 3 holes will not have enough air to burn correctly. Have seen this on MF 1150 that was smoking too much and had lost power.
