hi i"m having problems with my john deere 40 and think it may be the carb. before i had this major problem the tractor would bog down if 4th gear all of a sudden and then continue as if nothing happened. now the tractor is hard to start and when i try to put down the throttle is just does nothing and sitts at low idle and eventually goes into high idle.

Things to check before pulling out the real tools is these things. #1 check spark and make sure it is a blue/white and will jump a 1/4 inch gap. #2 check that the throttle linkage is working as it should be and not binding up some place. #3 check to be sure your air cleaner is not clogged up and or full of dirt/water. #4 open up the crab drain plug and make sure you have a good steady flow of gas out of it for a couple minutes. Catch the gas so as to look for dirt or water in it. #5 does choking it hurt or help?? If it hurts likely to be running to rich so set load needle down a 1/2 tun or so. If it help open the load needle up some
