Priming engine

I just replaced an oil pump shaft coupler on an unstyled A. I want to prime the engine. Is it true I can do so by just turning over the engine until pressure reads on the gauge? I would be able to build up enough pressure by turning the flywheel slowly or normally with out having to go crazy fast in turning the engine over?

Petcocks would be open. Do I have to take the spark plugs out?

Thanks
 
Take the spark plugs out. The compression release releases only a portion of
the compression. It will be much easier to turn with the plugs out. Squirt
some oil in the cylinders also.
 
If you want to THOROUGHLY pre-oil the engine, go out and buy a $15 garden sprayer and cut the end of the wand off and connect it with a hose to a hose barb screwed into the oil gauge port.

Put a couple of quarts of oil in the sprayer, pump it up, and oil away!

YES yes yes Bob and here is another. The oil filler on most engines is all of the way to the top of the oilable areas of the engine. Think about it. I filled an engine all of the way to the top with enough oil to do an oil change like three times. Let her sit over night as the oil goes every where in the gallies and pump. Drain it out and then put it where the level should be. Pump bottles work great too but fill er up is stone simple and you now are ahead two oil changes of oil.
