John Deere Hydro 175

I have a John Deere hydro 175 that starts and runs but shuts off when put under load. It appears to have good spark and fresh fuel and will run about 10 minutes at high speed but then just shuts off

picked this tractor up for free , got it running but every time had to spray carb to get going then ran fine. took carb apart looked cleaned reinstalled now will not run at all. You can spay directy into intake and back fires. Good spark , compression any ideas ? Are these carbs prone to going bad ? Plenty of gas from fuel pump as well. Thanks for any advice
