We have a 666 hydro gas. its about the sweetest tractor we've ever had, especially on the square baler.But its fuel consumption leaves much to desired. I know the hydro takes extra fuel, but it seems like it takes close to 4gal/hr doing anything. We have a 340 that will use 3gal/hr at full power, but is real economical when run at less than full power. Carb has been overhauled with a new main jet. But it seems like its always running abit rich. No adjustment on the electric shutoff main jet.I think I remember reading somewhere that there was an aftermarket kit that allowed you to adjust the mixture or in some fashion increase the fuel economy. Can anyone help me or am I remembering things I never saw? Thanks for any info.

I have a hydro70 gas. very thirsty but I only use on the feeder wagon so it only runs a short time. eengine runs very smooth and not rich at all. Only way it could be rich is too much fuel or not enough air. check air filter and carb float level and valve. stock jet should not cause rich condition
