I would not even consider a homeowner model from any brand. I do understand that you run mix gas in may of the 4 stroke hand held tools , but it adds complexity to the engine . This design came to be as a way for some companies that couldn’t really meet emission requirements with the higher displacement enginesStihl homeowner gas engines are 2 stroke. The commercial units are 4-mix engines, (except for the 94 series). A hybrid of 2 and 4 stroke engine design. They have valves like conventional 4 stroke engines, but run on 2 stroke mixed fuel, 50:1 ratio. This hybrid 4-mix engine was introduced 20 years ago.
Some brands like Troy bilt, Honda, etc. have a oiled crankcase and are heavier with more moving parts than the Stihl hybrid 4-mix engines.
Im not trying to be a internal combustion engine grammar nazi. I knew what you meant, just trying to be a little more specific for folks that are not in the industry.
On a side note, Echo has really steped up thier game in the past couple years.
I did not go into the tech side, not because I did not understand it , but for most users they simply don’t care. They want to pick up the tool , Start the engine and use it.
I cannot speak enough good things about the speed feed head used on Echo units. That design works so well
