Description from the creator

Metal in Motion shows you how to do a wet and dry compression test on small engines or powersports. Keep in mind that the compression release mechanism on most 4-stroke small engines will bleed off some of the compression during cranking for easier starting. Once the engine starts, that mechanism is disengaged. For this reason I prefer to do a leak down test, which we will be demonstrating in the next video.
