28 EFI Economy

I bought a 28EFI/60 inch about a month ago. The word was better economy. Today I ran both my 27/60 and the EFI side by side, and when we got home the 27 was running 1.22g/hr, and the EFI ran 1.33 g/hr. The 27 has 400 hours on it, while the EFI has just 35. Can I expect the economy to go up any once the engine has had a longer break in time?

If the efi doesn't get better fuel economy than the carburetor model you have a serious problem.

Well thats what Im hoping, better economy I mean. I asked the question to see if it should get better once the engine is broke in. I am sure it did worse the first 2 tank through it than my 27, I watched closely. I had heard anything from .75-1 g/hr, so hopefully with a few more hours on it I will be getting better.

Happy to report the EFI is definitely showing improvement. We ran the 27 and the 28EFI yesterday, and after 7 hours of use, the EFI used exactly 2 gallons less gas. Havent gotten an exact fuel rate, but it was definitely 2 gallons less on the same terrain.
