Was raking hay the other day and engine started surging, then wanted to die. Suspected it might be the carb, so hopped off and turned rich/lean adjustment screw out and after about half a turn, she smoothed out and ran fine after that. Trouble is that screw is almost loose enough to be floppy and problem may have developed by screwing itself in. Tried to tighten the smaller of the two nuts and it is more or less as far down as it is going. Does that have some form of packing in there that can be or needs to be replaced? Or......how does one firm that screw up so setting doesn't wander? I assume for best fuel economy for light duty use like raking hay, one wants it running as lean as it can? Right now it is about 3 turns out. |

3 turns out is normally i little excessive.. It might mean you have a little piece of crap plugging a jet inside.. I have wrapped teflon tape on the threads to tighten things up somewhat.. a coil spring under the screw head can also help... if it has a head on it..
