I have read other Efi horror stories on here before but I am having trouble with my Kohler EFI, been to the dealer 5 times-it will run good for a couple lawns and then losses power and sounds like crap. It seems to surge or barely run at all. I know other people on here have dealt with this before and I am wondering if anyone ever had their machine fixed or found a solution? Any suggestions would be appreciated, or should I just trade it in for a non-fuel injection model? It only has about 375 hours on it.
