My 2 N is acting up. It runs well for about 30 minutes and then starts coughing (like the governor is trying to adjust to the load). It spits and sputters and then sometimes dies. I have to limp back to the barn. While it spits and sputters it lurches and this is hard on me just having two back surgeries last part of last year. I did notice the governor is leaking some gas/fluid. Does the governor need a rebuild or replacement or is it maybe the carb? The carb seems to be running ok when it is running. I have cleaned out the gas tank, cleaned the filters, took the gas line off and cleaned it out. Also drained the carb. Any help is appreciated.
