I have a '52 8N that I can't seem to figure out recently what is going on when I start to mow. In the spring, the tractor did fine plowing and discing the garden. Since then, I have tried to mow my field and each time when the tractor gets under load with the bush hog running it starts to cough and spit like it is choking out. This is the same 5 ft bush hog I have used for years so that is not part of the change or new. It idles fine, coughs a little, but runs fine, about 3/4 throttle it starts to act up and then when you start to release the clutch to start to mow it wants to cough and cut off. When you open the throttle wide open, it coughs and sputters till it gets running full speed and then it will turn the mower and move. In the spring, I rebuilt the carburetor and I think I have had this problem since putting in the new needle valve that has the rubber tip. I have not touch the points or the timing since the tractor was doing fine before. I have adjusted the floats a couple times. I guess I have three questions, would putting the load on the tractor have any impact on the points or or the gap for the points? Could the governor be kicking in and flooding the tractor? Do you set the 1/4 inch of float height with or without the gasket on? I recently replaced the fuel bowl, fuel line, and filter that is in the top of the carburetor. It still has the same problem. I really think this is a fuel problem the way it coughs and sputters. Had the carburetor apart, blew air and carb cleaner through all the little holes. Set the air intake to a turn and half and let it sit. Looking for any other thoughts.
Thanks,
Rob
