How long do i need to run the drill motor to prime the engine after i have primed the oil pump,did the timing chain thing today had a little trouble getting oil sucked into pump at first ( put oil in radiator oil line in wrong place) when i finally did get it primed the drill got in a bind and i run it like that for about 3-5 min. ( my hand got tired) just asking to see if i did it right or not thanks
