Blue smoke indicates burning oil. It can come from improperly seated rings or too much clearance in the valve stem guides, although it is possible that you just need a break in period for the rings to seat. I noticed more smoke than I expected after my rebuild but not noticeably blue. However it did not seem to continue smoking. Just a thought but you might check the spark plugs. My guess is that if one is fouled more than the others it would indicate a problem with the rings or guides in that cylinder. Lighter fouling on all the plugs may be just indicate the need for more of a break in period. You might check the Guest Log section of the Moyer Marine web site to see if anyone else has asked the same question. If not ask yourself. Don seems to be very willing to answer questions, even about engines someone else rebuilt.
