Ive checked the valves to make sure they wasnt stuck,checked the fire,put new plug in
SOURCE: my john deere 345 shuts down while running.
check the tank for debris blocking fuel outlet. also change fuel cap as it could be pulling a vacuum on the tank.
SOURCE: 3020 carburetor ? john deere gas tractor, 3020
those carbs are real simple you will not have any problem
SOURCE: My John Deere X320 has gas fires up, but will not
It sound like a service problem. Change fuel filter. If when you pull the line there is gas there but it goes back to the tank.ITS a vent problem. IF no change then the fuel pump could be bad or a possible pickup problem
SOURCE: I have a John deere 317 tractor that does not start.
We will be testing for voltage to the points, coil, engine to tractor wiring harness, ignition switch
Tools needed:
volt meter to read 12 volts, or test light
1) with the points open: is there voltage at the connection wire at the points
If yes; adjust points to .020" and try to crank engine and check for spark
*** you may want to determine if condensor is connected to this wire also
if no
2) check point side (neg or - ) of coil for voltage
if yes, engine should start
if no
3) check for voltage at the + side of coil
If yes, coil is bad
if no
4) check wire connector from engine to frame wiring harness
if yes; engine should start
if no
5) check wiring on the back of ignition switch
if yes; engine should start
if no
6) check that ignition switch RED or BATTERY supply wire has voltage
if yes; switch is bad
if no
7) check supply wire and circuit breaker connected to the battery side of the solenoid
if yes; engine should start
if no; circuit breaker could be at fault or wire connector at battery supply

If you have gas running down to the carberator ( take the fuel line off and make sure there is gas running to it or there may be a screen or filter plugged by the tank or on the way to the carb) if there is gas there the problem lies in the carb itself. If you have some mechanical ability you should be all right as it is not rocket science. If you are comfortable with taking the carb apart the first thing i would check is the needle vavle. With the carb apart you will see a big brass looking thing this is the float, right above that is the neddle valve, that is the first place they seem to stick on me. Move the float up and down if the neddle above it doesn't move or sticks there is your problem. Spray it with carb cleaner and see if it moves freely. You may have to dismantle the carb to get it to work freely. If it won't buy a carb kit and install all the new gaskets needle valves and jets ( this is a very good ideal any how) Also make sure any little ports in the carb are open ( in the bottom of the carb there may be tiny little holes that are plugged) find a very small wire to clean them with and also make sure when you are done you can spray carb cleaner thru them. This is why they have a small straw on the can with it ( watch your eyes and wear safety glasses as you never know where it will spray out from) That stuff will dry your skin out fast so don't get it in your eyes and you may want to wear rubber gloves. Also be very careful when putting back together as there are little pieces that like to slide around and fall out or may get bent even worse you don't want them in your motor. Also try to count every screw you turn as these are jets and you will want to put them back to the place they were set at cause it's a pain to get them set right by adjusting them later. Do not force anything putting it back as you may bend the jets or float and you will have to take it apart again and replace them as well. Take your time and be patient and you will be just fine
Testimonial: "thanks...you gave me encouragement to give it a try. I took off the shroud, air cleaner box and couldn't take off the carb as there are no heads on the four bolts that hold it on. Looks like it was designed not to be removed? I took off an inspection plate on top of the carb and cleaned all of the channels and ports within with carb cleaner and compressed air...still no gas flowing thru carb...unless I force with compressed air. Any other thoughts? It is a twin cylinder OHV B/S. Thank you. "
