With both valves closed, and front piston coming up on compression stroke the front pump tappet/plunger will be coming up also. The spill timing is done with the delivery valve and spring out, pump rack in run position. I'm not sure what engine timing spec is, but let's use 20 degrees BTDC for example. At 25 BTDC the pump outlet SHOULD have fuel flowing out, and flow should just stop when engine is turned to 20 BTDC as plunger JUST closes off the barrel inlet port if pump timing is correct. I usually back engine up to about 40 degrees BTDC so flow starts again, then turn engine slowly until flow just stops to re-check the setting. This method is for PORT CLOSING injection pumps which are common. The PORT OPENING pumps are done differently. Also note rack MUST be in run position, if in STOP position flow will NEVER stop to set timing.
