Victa lost the argument years ago. I remember part of the counter to the invasion of 4 strokes in the 1970's was an advertisement entitled, "It just doesn't make sense" and it then went on to list the advantages of the 2 stroke engine against the 4's. It wasn't enough and people chose 4 strokes that were quieter and seemingly less troublesome.
I am still a fan of the 2 stroke engine and love repairing old Victa's but I do find them harder to sell and I often get,"I don't want to be mixing fuel ..blah..blah". Then I wonder how they work their trimmers.
