Do you have this book? Page 71 has the info. Hopefully you can read the pic I posted. Is your injection pump ready to install? I am very rusty when it comes to inj. pumps, since I may do one every 5 years or so. But basically, with the pump off, you set the timing mark on the the flywheel . Lets say the timing is 5 degrees, you set the flywheel to 5 1/2 degrees. then with the Kent Moore timing tool, you rotate the pump til both A+B lights are lit at the same time. then install it to the engine. Install 2 bolts in the pump drive gear. re-install the timing tool, and back the engine up about 30+ degrees, and rotate it clockwise slowly until both lights are on at the same time, look at the timing mark on the flywheel at this time and should be right on 5 degrees. If timing is off, roll the engine back again, then forward to the correct timing mark on the flywheel,,, loosen the 2 bolts in the pump gear install 2 long bolts in the 2 open gear holes (unless you have the spanner tool), and use a long screwdriver or skinny bar to rotate the pump ( do not let the engine roll over) until both lights are lit. lock it down, then roll it back 30+ degrees again and then clockwise til lights come on, then timing should be right... I don't know of another, better or easier way,. Mabey someone else can fill in any blanks i created, Jojo
