So I am trying to figure this out... With the raise in gas prices why are the manufactures coming out with big blocks on mowers that still have carbs. I mean I figure cost is a big thing but I think its completely ridiculous. The auto industry is switching to turbos and direct injection. Why not make these 37 hp Kaws, 40 hp Kohlers, and 35 hp Briggs with EFI? Manufactures please chime in here... I would love to pay 500 more for a more efficient machine if I know it will save me later in life on my operating costs. Plus, manufactures, wouldn't this help you in the service department to? Example: Jo is having a problem with his mower... he would have to take it to the dealership instead of Phil's mower repair right? I don't know, I'm just thinking out loud.
