timing

Hi, I'm about to start working on the injection pump on my Ford 3000, 1967, diesel, Simms/Minimec injection pump. To do so, I have to turn the engine to the 19deg btdc mark on the flywheel and compression stroke cylinder 1. The only way I can see to know it's compression stroke for cylinder 1...

just installed a new injection pump from circle g tractors did gears new to went by the limited instructions they gave me (they could use some help) so i got the tractor running but heavy smoke kept moving back and forth on slotted gear to where i felt it was running best it idles and revs up...
