What started out as a 641 with a bad engine we changed over to 5speed and 172 engine got held up because of having wrong flywheel. Before Christmas we got the correct flywheel installed and started putting it back together. Today we worked at it and got it fired up and drove it around the yard. everything worked fine.Just a little noise in reverse. Not sure what that is. Plan is to finish it up before New Years Day unless deer hunting gets in the way.
