Yeah, older two strokes can burn too much oil. They probably just need a tune. Actually these days a lot of the more modern ones are 4 stroke engines now. These are quieter, and supposedly more reliable (?) but 2 strokes are more fun IMO. More bang for the buck. All the really fast ones are 2 stroke.narlus said:probably, esp the older ones. they always seem to be trailing blue plumes of smoke.
