Stop in for a cup of coffee

it sure should have -so, is there anything to this statement? seems like total poppy-**** to me..
Machine shop told me never prime the motor as you just washed off all the assembly lube which stays in place better if the motor doesn't start right away.
I will say I have put together engines without priming, with great success. Some engines you cant prime. But if able to be primed I prime.
