This engine still uses points and condensor, so both were replaced. The point gap was set at .022, and the dwell was checked with the engine running to ensure it was correct. The dwell will show if the proper point gap is set. Cars in the 80 did not see old style ignition systems like this (they went electronic around 75) but the boats still use them. I will eventually update this distributor with an electronic unit in the future. The conversion kit installs in place of the points and condensor, and will not wear out like points do. A lot of automotive mechanics today have no clue about point type ignitions, and look at a dwell meter like it is a UFO. I still own a dwell meter and timing light, and they sure did come in handy. The cap and rotor were also replaced.
