Flooded John Deere G

Hello, I have a 1950 G and the float stuck open and flooded the cylinders. What would be the best way to clean the gas out before trying to turn it over to start it. Thank you.
 
Pull the spark plugs, make sure the ignition is off, hand turn the engine through several times to push the gas out of the cylinders.

You probably have gas in the oil too. I would drain the oil, let it drain overnight to get the remainder of the gas out of the cylinders.

Refill the oil, bump the starter through a few times, then spin it to blow any gas out the plug holes. Again, be sure to disable the ignition, don't want any sparks for obvious reasons!

Then put a few squirts of oil in each cylinder, spin the starter again. Put the plugs in and give it a try.
 
Ground out the coil or mag, don't know what you have mag or distributor. Just make sure you have no spark. Take out the spark plugs and
turn the engine over. Gas will come out the plug holes. Better check the oil and see if you have gas in the engine oil, don't recommend running
it if you do!
 
y N Shephard,Be sure tank is shut off.Is the float still stuck open,the float could have a hole in it and filled with gas.Check the oil level first to see if it over full or gas contaminated.If the float is ok,remove air cleaner bottom and check it for gas,pull both plugs and crank the engine over with the ignition switch (OFF) to prevent any fires,crank it over several times to blow any fuel out.Then let it set for say 1/2 hour to dry out.Burn ends of fouled plugs with propane torch,or replace them.Put plugs back and crank it up then turn on the gas.
 
Does it have peacocks down under the block like a late A? If so open the peacocks and crank it over to blow the gas out. No need to remove the plugs then. Then change the oil.
 
Like the others have said, pull the plugs and make darn sure the ignition system is disabled and wind her up with the starter or pull it over by hand many times if it is a hand start tractor. Do not allow it to make spark. If it does you will have a fire that you may not get out until it is badly damaged. Fix the carb and change the oil as it likely diluted the oil with gas. Dry out the plugs and let her rip. Good practice when shutting these old two cylinder Deere's down is to shut of the fuel off at the tank and let it run out of gas and then turn off the ignition if it has distributor. The needle and seat leaking on these is a common problem. Not a bad thing if you turn of the fuel supply and let the carb run out of gas. They will only run about a minute or so. Throw the can on the stack and go eat dinner.

Jim, the Gs never had the petcocks on the bottom of the block like the As and Bs. They were on the side of the block all the way through G production.
 
It will take a lot of turning over to blow all the gas out like others are telling you. Use an air hose in the petcock with the spark plug removed. Turn it over till the piston just starts to cover
the petcock hole and then it will have all the gas near the front.
 
Ours sprayed fuel out all over the front of my Dad, then the fuel ignited. Dad started to run away' I had to run him down and roll him in the dirt. It took him a year to recover from the burns.

The next time the engine seized, a sand hole had opened up and flooded one cylinder full of coolant. That was just a plain disgusting tractor. It was also the last JD tractor on the place!!!
 
To add a few things 1. change the oil I had this happen before it put gallons of gas in the oil. 2. pull plugs and petcocks use air and eather (or similar spray clean). Let tractor set for a while to evaporate like over night. BE VERY CARFULL OF WAVING TORCH OVER PLUG HOLE AND OTHER SUCH METHODS AS YOU MIGHT HAVE A BALL OF FIRE!!!
 
I have a 8C Cat 20 with a similar (smaller) ensign carburator. It has a cork float. Cork floats were traditionally sealed with shellac. Ethanol in the gas eats shellac, I am on the search for a brass float.
 
petcock opening is not big enough. Had that happen once on the 38 A. Turned by hand till could get it to turn over, then put belt on and run that a little while with wire pulled out of mag, changed oil and was out in field in hour.
