hi gentlemen and ladies,some history: about 1960 801 Powermaster. when I bought the tractor it had a habit of throttle surging, in a sort of shallow sine wave, up and down. It smoothed out under load, though, and I could work the machine hard. Last summer I had the flywheel weights in the distributor replaced. The guy who fixed it did this to get it to run, he said they were almost worn away, AND he replaced them with some he found lying around his shop. He said the alternative was a new distributor for around $500. After he did this, the machine would start and run fine, BUT when I put a medium load on it, like say, tilling 6 inches deep, it falters and wants to die. It's nowhere near as powerful as before. However, occasionally it surges with power, when the governor kicks in. For another reason (sugar in the gas a little over a month ago), I recently had the carb rebuilt and cleaned, put the carb back on and it runs fine again, with maybe a little more power than before, but still underpowered. However the surging is a little different. I can see the governor arm kick in and out in a rapid stutter, maybe once every 2-4 seconds, even unloaded. I adjusted the throttle linkage to pull the governor the maximum forward, toward the carb, but it still surges. Due to the sugar, I installed another inline throwaway filter in the fuel line. Could this be starving the carburetor of gas? Easy to test, I guess, but it's performance is about the same as before the sugar incident, i.e., falters under load, but with occasional surges of power. If i could get the governor to engage and stay engaged when it's heavily loaded, it would be back up to par. thanks so much in advance Andy
