New to the group & fairly new to tractors.... I have a 640 that has just started not wanting to run for very long. New battery, starter, selonoid, points, plugs, wires and fuel tank. Starts right up and runs nice for about 15-20 minutes while bush hogging then suddenly misses, spits & sputters. If I push in the clutch it will idle fine until I release the clutch and when it gets a bit of a load from the brush cutter it again sputters and wants to shut down. After a few minutes it stops. Let it sit for a few minutes it starts right up - start cutting and after less than 5 minutes same thing. I was able to get it to the carport and it kept running great until I tried engaging the cutter and release the clutch with it in 1st gear. I ran it 2 days ago for about 3 hours and not even a hiccup. And there is about 4 inches of fresh fuel in the tank. Thoughts, suggestions, solutions greatly appreciated. Jeff
