I have recently acquired a Ferguson TE20 (tvo/petrol). Am experiencing some difficulty in starting it. Sometimes it fires after 3-4 turns, other times it turns over to the point of running the battery down and doesn't start. Sometimes when turning over, petrol drips from the underside of the carb, don't know why. Some sparking difficulties experienced at the plugs appeared to have been cured when plugs where cleaned and some corrosion was removed from coil. Tractor started easily. However next day problem was back. Any suggestions as to what to do next?

yup all good advice and all should help,, I have a little trick when mine doesnt start right away and see the gas running out of the carb,, I shut off the gas,, then when she starts I turn it back on,, at least it stops the gas from running through, and there is normally enough gas to start her.. works most of the time unless I dont "catch" it quick enuff,, they all start different,a nd it seems just a little off thye norm and they play tricks on you,pat

I have two TE20's and they both work the same when starting. When turning on the gas at the shut off under the tank, I can only turn the shut off knob one(1) complete turn. Any more than that and the carb. floods and the tractor is difficult to start. Also, as was stated earlier make sure you shut off gas supply when not running.

Nigel,

Like some of the previous comments, I believe it is flooding from the float valve most likely. Even if shutting off the supply at the tank, the fuel left in the carb leaks out into the air intake chamber and your tractor is flooded when you start. If this is the case, open the throttle completely when starting and it will most likely clear and start after a few trials. Before I replaced my float valve, I was removing the air intake hose and letting the gas drain out. Then it started immmediately.

Fuel from carb sounds like flooding. Ensure that float in carb is not sticking. Also, almost all of these old tractors have quirks related to starting. Each time the owner changes, the new owner has to learn "how to hold his mouth" to start it easily. I have a Ford NAA that only starts, even hot, if you pull the choke just for an instant, only one or two turns of the starter and then push the choke off, etc., and I'm sure other folks have some similar issues with one or more of their tractors. But if you have plugs fouling, you could have other problems. Do you have oil on the plugs? It's not clear to me the nature of the sparking problem based on your description.

Phil thanks for your comments. Originally I had to attack the plugs with a wire brush to remove a lot of caked on gunk. Any subsequent problems with the plugs has been them getting wet (with I assume petrol, it doesn't look like oil). Recently I was not getting a spark at the first plug in line, that is when I removed some corrosion from inside the coil. This resulted in a spark and the tractor starting very quickly. Next day (yesterday) however the tractor would not start, I actually flattened the battery trying and I will not be able to try again until tonight having had the battery on charge.

Fuel on the plugs does indeed indicate you are not getting good spark. In addition to the coil, check the points and also the ignition timing. A quick thing to do is to replace plugs and plug wires. Sometimes it is the wires that are bad. Use copper center wires, not the automotive kind which are made to eliminate radio static. Also, there is a surefire and safe way to jump start a six volt tractor from a 12 volt vehicle, which you can find in the archives, or email me at kanunorth@aol.com and I will tell you if you need to know that.

As Phil said it sounds like flooding. Do you turn the gas off at the fuel tank when tractors is not in use? On my TO if this happens I shut the fuel off at the tank and then drain the carb. float bowl. I don't know if it is easy to drain TE float bowl but if it is that is what I would try.

Those old carbs used brass needle and seats. a certain amount of fuel always leaks by. That is why it is paramount to close the tap every time the machine is shut down. The surplus fuel washes the bores and contaminates the oil. Severe engine damage will eventually result. If it is overfueling, you should see black smoke when it does start.
From your symptoms of hard starting, I would also take a good look at the points.
