Can someone help me time the Mimec fuel pump on this 1973 4cyl engine. The manual I downloaded shows timing marks on the back side of the flywheel(very poor picture). My engine does not seem to have these marks. I brought engine to TDC #1 using valve overlap. There is no marks I can see and I rotated flywheel 360. So I lined up marks on inj pump to drive gear and reinstalled in same place. Engine starts and runs but you can tell it is off. I am a heavy truck mechanic and have removed and reinstalled many pumps on Cats, Cummins, Perkins etc engines. It's not rocket science. The manual says engine is timed at 19 degrees BTC. There does not seem to be a timing mark on flywheel in this general area either. If I have to I will time it by ear. There is no other marks that I can find to indicate a true TDC or timing point on the engine. Any suggestions?
