If it was working before, there is no need to worry about the firing order as that never changes. Things to look at;
Clean and correctly gapped spark plugs,
Clean gas,
Fuel filter?
and a clean carburetor, float bowl and jets.

JOHN DEERE 3020 Gas and Diesel Tractor Service Manual

https://www.ebay.com > itm > JOHN-DEERE-3020-Gas...

This is a new reprint of John Deere Service Manual SM2041 for the John Deere 3000 Series Tractors shown above. It is dated June 1961. Includes 3010 & 3020.

There is a distinct possibility that this tractor was originally equipped with a 6 volt system. If it has been upgraded to a 12 volt starter, the ignition will need to have a resistor installed to bring it back to 6 volts.
I could be all wrong on this but it's worth checking.

remove the upper engine cover and inspect for a build up of grass and or a mouse nest that would over heat the coil and the engine

GY20473 gas tank from deere had a cap with a vent. GY21102 tank had a vent hose and was the later version. My guess is that you have the early version of the tank with the newest fuel cap. I recommend a new cap with a vent or drill a 1/32 hole in the top of the cap.
Problem solved

Thanks

From the rear of machine look at the top left of fuel tank for the fuel line.Where line comes out of tank see if it is pinched where it goes down between frame and tank,grab line and see if it moves freely.If that is OK loosen fuel cap after 10 minutes of run time to see if your vent hole in cap is working.These are 2 common problems for the L series mowers.

Loosen fuel cap 1 turn to see if it will stay running.Theres a tank breather hole/vent in the cap and when it becomes plugged no air can get into fuel tank when fuel is used,can also be a plugged fuel filter.

I have a 115 john deere tractor that runs but the engine will not run smooth I've put a new fuel cap on it a new pump and clean out the carb.

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.

You have dirt in the fuel tank and it sucks the dirt up on the filter that is attached to the pump. After the machine stalls, the dirt falls off and it will restart and run for a few min.
