Question about John Deere 420,1020,2010,2020,2510,2520 Tractor Float
Just replaced all the fuel lines and the fuel filter but it wasn't running before i did that i just replaced them all because i was meaning to anyways. the inlet(elbow fitting) from the fuel pump seems to be lose when i jiggle it a little fuel comes out the fuel pump seems to be working when i run it with out being connected it drops a few drops i don't know how much its supposed to flow so im not actually sure if that's how it should be. it did sit awhile so i was told to blow into the gas tank to push sum gas up and wet everything again i actually did have it running to day for a bout 5 min i made a lap around my back yard then i turned it off to open the gate to the front yard and i couldn't get it going again so im back to the beginning.

The easiest way is to not remove the tank. Buy a can of chem tool the liquid,not spray.Drain gas out of tank,pour can in tank,let sit for 15minutes,then drain,should clean it out good.

Have had to replace fuel line in tank MANY times do to it being split just above pump.Try doing a fuel pressure test on the return hose from throttle body,should be close to at least 40psi.

You may try blowing backwards from behind the fuel filter into the gas line. Not to much air pressure though. Make sure the gas cap is off.

SOURCE: John Deere will not start.
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. "
Chk the fuel by draing the carb bowl and the black thing may bea ck valve. Remove it and see what happens. Oh! drain the old fuel entirely and fill with fresh fuel. Good Luck
