Yes it does and it starts to produce a burning smell after awhile. Probably ran for 2 minutes straight. Perhaps not enough?

It has been discussed before, but it's hard to underestimate how much power is needed to turn an oil pump when priming. To illustrate, I use a 25 year old variable speed 1/2" Sears drill that is rated @ 3/4 hp for this task. I have to bury the trigger and hold on tight as the torque tries to twist it out of my hands.

In my case, is priming even necessary?

Can't kill those old Craftsman drills. I have 1 from the 60s, 500 rpm and I use it. I usually set it so the firewall prevents it from spinning so I don't have to fight the torque and leave it run till I get pressure at both bottom, top and push rods. Figure 500 rpm on pump =s 1000rpm engine. Sometimes it takes a while to prime
