Farmall Super C

I have a farmall Super C that I have done work on. I tried to pull start it a few weeks ago and I couldn't get it to start so I rebuilt the carb on it and tried to pull it again. It still wont start and this time I noticed that oil from the engine is leaking from the top of the exhaust manifold where my muffler connects. When I pull it then it just sits and tries to turn over but if you stop or push the clutch back in it dies. When I pull out the choke it makes it sound more like its going to start but it doesn't do anything. Does anyone have any ideas on why its not starting? And maybe why its leaking?

Lots of things can keep it from starting.

Any history on the tractor? Have you ever seen it run? What all was done so far?

Have you checked the basics, spark at the plugs and ignition timing, fuel, compression?

For a good indicator of the basic condition of the engine, disconnect the air cleaner from the carb, hold your hand tightly over the air inlet of the carb and crank on the engine. You should get a steady, strong vacuum against your hand, and have fuel on your hand when done.

Might try starting it with the air cleaner disconnected. Sometimes they get clogged with dirt dobbers or mice nests. There is also a wire mesh that is often overlooked.

As for the oil out the exhaust, that may be carbon and gas dripping back down from raw gas passing through unburned while pulling it. Something to check though is the oil level. Be sure it isn't overfilled from gas contamination, especially if the carb was flooding.

If you suspect it may have been flooded with gas, pull the plugs, take a look at them. Even if new, they will tell a story. If they are sooty black, it is way rich or flooding. They may need to be cleaned.

If the plugs are clean, not wet with fuel after a choke assisted attempted start, there may not be fuel coming to/through the carb. (Remember the wet hand test above.) There is a drain plug in the bottom of the carb. With the fuel valve open, remove the plug, catch the flow in a clean glass. You should get a full flow, then slow as the bowl empties, but continue to trickle, not stop or slow to a drip. Look at what was caught. Should be relatively clean, no rust flakes or noticeable water on bottom. Be sure the sediment bowl screen is in place and clean.

Do some basic checks, let us know...

Hello Kyle, welcome to YT! Steve has done a pretty good job of giving a list of suggestions. The trouble with diagnosis over the web is we ?experts? (lol) have no idea of the amount of mechanical knowledge a person has who is posting the question. You could be a 14 year old who just thought that getting this tractor to run would be great; all the way up to a seasoned farmer/ mechanic with a reasonable amount of mechanical knowledge. So that inpart is what Steve is trying to glean from the background story of this tractor. Please don?t take any suggestions as trying to put you down in anyway. One thing I will add to Steve?s list is the fact that on Farmalls the fitting in the carb where the fuel line hooks to contains a screen that needs to be checked for being clear. You may have found it while rebuilding the carb, but often the screen gets overlooked. What you think is oil coming from the exhaust may be unburned gas mixed with carbon, maybe not totally alarming considering you have tried pull starting it quite a bit. One thing that is sort of frustrating when giving help on a forum is when you get no reply after providing help suggestions. It is just that a little gratification is nice once in a while to prove you did some good for someone. Good luck!
