Good moring! I have a 574 gas that is running rough-sounded like it was missing or not all cylinders were functioning well-and I can not figure out what is going on. Here is what I know and did.
I checked the spark plugs and notice they all were covered in a thin, dry carbon film so I cleaned them, and regapped them. Checked all fluids-oil was good, radiator was low, so I added to full. I ran them for an hour or so and the tractor ran well but the "chugging" returned.
The spark plugs were covered in the dry, carbon film so I put in new spark plugs-Autolite 3116, points-gapped them to spec 0.02, condenser, rotor, and distrubutor cap. One spark plug wire, #2, didn't have a wire coming out of insulation and bent over the clip. So I fixed that.
I ran the engine and sounded more like normal, but after using a 7" sickle mower to trim under the fence for maybe 30-40 minutes, so "chugging" returned under lower idle. I went to finish mowing out a field drive and the problem worsened-loss of power, darker smoke out of the muffler, "chugging" along, limping back home.
This morning I took out the new spark plugs and they are coated with a light film of dry, black soot just the same as what is at the end of the muffler.
I am thinking the worse here but I was hoping someone may have more thoughts as to what is wrong with my 574. I bought my trator 4 years ago, 3240 hrs, light duty work for me, ran like a top. Thank you for thoughts and ideas!
