Mike, block the carb means that the throttle blades are all the way open, and you do whatever you have to do, to keep them open during the compression test. Yes you don't want an accidental spark to ignite anything. Also all plugs have to be out of the engine to get a true reading. The only reason to squirt oil into the cylinder is if you have a low reading...
