Is there a way to reduce piston slap on sj413...apart from from a possible rebore........
start up noise then dies right down after a few miles when engine warms up
mileage 90 thousand......using correct grade of oil......hesitate to use a thicker oil as some of the clearances on engine are close...................noticed if i depart from the correct ignition timing the rattle is reduced on start up....(retarding)
No blue smoke at all, uses very little oil
