sound like the pump is bad under pressure . take a old gas tank hook it directly to carb and gravity feed it start engine . if it runs fine then it is pump if not then you need to pull carb.
I agree with JL, start by bypassing everything and hooking straight to the carb. If you can run the same amount of time or longer at full throttle like your having problems, then signs point to a pump. On the other hand, a good rebuild never hurt anyone. Its very possible you have a piece of rubber fuel line the deteriorated and is lodged in the pump or in one of your needles. My k361 was a PIA to pull carb off and clean out bowl, float and high and low speed needles. I used a mic to make sure I got the needles set back at factory.
How long did the tractor sit, before you got it? Any ideas? Could still have some bad fuel or varnish build up that's clogging system. Just my 02 cents
