Bringing this up just for the hell of it : looking over some old posts , and came across this quote : " Your average 4 stroke motor was rated at 500 engine hours, were the 2 stroke motors were rated at 200-250 engine hours of life expectancy before requiring major repair " I`m a big 2 cycle fan . I had a Toro mower with Suzuki motor , from 1989 until 2011 , 5/8 acre , 70 -75 minutes each time . Averaging 26 per season , I figure around 700 hours , and was still running when I sold . I`m thinking my Duraforce Lawn Boys capable of the same . Any thoughts ?

totally depends on how an engine is used and cared for.

It depends, upon a lot of things. How good is the engine to begin with? How is the equipment used and how often? How is the equipment maintained? Sometimes equipment will have a sticker on it with an hour rating. That is how long it is rated to stay within EPA standards. Lucky to get 3-5 years out of a cheap 2-stroke trimmer. Not uncommon for 30-40 year old Stihl chainsaws (2-stroke) to come in the shop.
