I am working on an Oliver mid 70s 1955 I think, can't find a serial number, it has a Roosa Masters injection pump, can anyone tell me the step to timing the pump?

You need to get #1 on compression stroke at say TDC since timing is 2 degrees before. Remember your mark (TDC) on the flywheel is for cylinders 1 & 6. Don't worry about any marks on any pump drive gears. Get your marks in the timing window to line up. Bolt it up, roll it back a 1/4 turn to take the backlash out and roll it in the direction of engine rotation till the marks in the timing window line up. Check the mark on the flywheel and rock the pump as necessary. Tighten it down, bleed it out ( I hope you put new filter(s) on. Good shop practice: pump work equals install new filters. Unless the pump tied up see why it is much easier to line the marks up in the window remove the pump and if you did not trurn the engine you are close. J.
