** Smoke is blue & smells like I would expect oil smoke to smell like. Crank was serviced with five qts. of Brad Penn break-in oil plus one for the 1 qt. filter. Correct road draft tube is installed. Will pull the plugs and update first thing tomorrow morning. ** Just as a note the engine was rebuilt by a so called machine/over-haul shop but has been setting in my shop for a year covered up.
