I have noticed a significant loss of power in my 1948 John Deere B over the last several months. I had used it to pull out logs and push snow last winter and it had plenty of power. However, this summer I noticed that the tractor would stall under load. When I sank the cultivator (7 ft ferguson 3 pt cultivator, not a chisel) the tractor would come to a stop. The engine wouldnt shut off and it wouldnt labor, but it simply was stopped dead. So I rebuilt the carb which had some rust and dirt inside and the main nozzle had two clogged holes. However, I encountered the same loss of power this morning. Again, I was using the cultivator to stir up some soil in the garden to plant a cover crop. The tractor ran fine for several minutes sinking the cultivator to the desired depth. However, after about five minutes of work, the tractor would simply not pull the cultivator any longer. Could this indicate a deficient magneto coil or low engine compression? Any advice is welcome.
