The dealer replaced on warrantee, the ethenol gas is creating havoc with the float. Had to have it replaced twice. Problem is being fixed at Ferris.
I opened up a can of worms dissing ethanol fuel in another thread( a couple of users here would argue til they're blue in the face that ethanol has nothing to do with your problem:0)
Can you get non-ethanol fuel in your area?? I have a new(2012 model with 23.5 hours) Gravely and I won't put anything except 89 Octane non-ethanol fuel(with Sta-Bil fuel stablizer to boot) in it's gas tank(I don't care how much more expensive than ethanol blended gas it is)!!! I'm convince ethanol is BAD for any engine(but more so small engines) and I'm not going to spend several thousand dollars on something and then take a chance ruining it. Have you considered running non-ethanol in that Ferris??? I would recommend you give it a try if you can get it in your area. You'll also notice more cuts on a tankful of gas!!!
