I’m working on an 1810 for someone. I’m supposed to be fixing a leak in the rear end, but it is also not running. Never tried to start it when I went to pick it up, we just pushed it onto the trailer, he didn’t say anything about it not running. When he said the tractor doesn’t move, I thought he just meant it was out of fluid, and runs but doesn’t move, but I couldn’t get it to start. I wanted to take it outside and wash it, then drive it around and see if I can figure out where it’s leaking from. I noticed gas coming out of the muffler, checked and the crankcase is full of gas. Should I start with the carb or fuel pump? I don’t want to just start throwing parts at it, and definitely don’t want to blow the motor on someone else’s tractor. Obviously I will have to change the oil before I can run it.
