On priming the oil pumpÖ. Some engine builders recommend Vaseline, some just motor oil, some assembly lube. I donít think itís a major issue as long as some lubrication is in the pump and you donít pack it with some kind of grease that is thicker than Vaseline. Vaseline dissolves quickly once itís mixes with motor oil.
Yeah... spark plug removed to crank engine to get oil pressure up before first firing.
