Doesn't seem too bad except or one thing, all of the black in front of the muffler tells me it's either running very rich or burns a lot of oil.

Not necessarily.

Thats just carbon. Happens on every old tractor with exhaust that blows onto sheet metal.

I have had dozens of non smoker tractors do that!

Infact, I have one now that doesn't smoke that has a black hood. All depends on where the exhaust tip is directed. Engine tech is wayy different these days:)

:rolling:

I bought a Case 222 one time that looked like that.  Hood by the exhaust was black.  Guy said he put in new points, condenser, rebuilt the carb, and still couldn't make it run right.  His wife's grandparents bought it new and he knew he should not sell it but couldn't make it run correctly and gave up.   It was obvious it was running rich.

Got it home and I could see he had done the repairs he said.  Carb was clean and adjusted correctly if it was able to breathe, and actually ran quite well with the plugged air filter removed.

I believe he tried to wash the air filter out, imbedding the dirt IN the paper and pretty much sealing it off.  :(

New carb? Bet it's a cheap replacement Walbro carb.K series Kohlers either run super rich or super lean with the Walbro carbs.If you can get them set to throttle up correctly they won't idle worth a darn unless you set it to run really rich.

I suppose leaving the choke on a lil to long ain't gonna help matters either, but looking at the pipe when it's running will tell you exactly whats going on, if anything.

What are you thinking?

Did u ever cut open a muffler from a supposed good running engine, car, truck, motorcycle, or whatever? 

There is a reason the tailpipe on your car is pointed away from the body. Not only would it ruin the paint, but it would turn black!!

Thats just carbon.

Which means it is running rich, one of the options he gave in the first place.

Look up the tailpipe of your vehicle. Does it run good, I bet it does, but its black inside. Gasoline is carbon based, its going to give off soot NO matter how its tuned.

No matter what, if that tractor runs, sounds, and don't smoke like a skeeter fogger, I'd buy it.

Cheers;)

Combustion is a very well understood chemical reaction.  Complete combustion will only have carbon in the form of carbon dioxide.  Incomplete combustion is the result of insufficient oxygen, which results in unburned fuel being exhausted.  There's a big difference between tiny trace amounts from nearly complete combustion, and a huge black mess like that photo.  https://www.referenc...e75ca7bbdbd8fab
