I think you will fine it depends on where you live, the first 066 I seen here was in the late of 1990 but was taken back because it didnot work well in the snow, they changed the covers on the saws, I bought 3-066's in the summer of 1991, they had the same covers as the 064 on them , you could not keep coils in them , maybe you would get 3 or 4 days before they went south so I put 064 coils in them and rotated the flywheel so they were timed correct, happy days after that
