It's been a while since I logged on. I hope everyone is doing great. Some of you may remember when I bought this gravely? Anyway, it's been a great machine until a little while ago. I was cutting grass and it just starting cutting out. I cleaned the fuel lines and the tanks in case of debris (the fuel lines are new, black, from Gravely. The old ones rotted away), replace the fuel filter. This did not help at all. Then I pulled the carb and cleaned it the best I could without actually taking it completely apart. This seems to do the trick. It ran great for a few weeks and then suddenly my problem returned. I instantly pulled the carb and cleaned it again but this time it did not help. Here are my symptoms: Idles fine Runs good when going straight most of the time, but when I spin around it almost dies, then sputters for a bit and picks back up. Sometimes it struggles for a while before it picks back up. The fuel filter has only a little bit of fuel in it. If I disengage the blades and let it idle for a minute or two, it runs great for a few minutes after I re-engage the blades and cut. I'm thinking maybe the fuel pump is bad? Anyone had a problem like this before?
