I did run it but not extremely hard.

I ran it for a while with the new gas in the tank.


In my humble opinion, you have not worked it near hard enough or long enough to see significant results. Putting around the neighborhood ain't gonna get it. Plow or disk a field. Mow five acres of tall weeds. Plow some snow this winter.

... she is smoking but about 1/4 as much.


You are starting to see some results. Relax and continue with the Seafoam treatment. You're not going to see amazing results over night.

Thanks for the reply!

Its a 71 that was used to cut grass. ( I was told ) Tractor was shed kept. Engine cranks
and runs great. No noise at all. I think the carb is a little rich. I hate to pull the engine. I
use it to break and disk my garden along with other around the house work.

I think most are, except the ones that do real work like pulling a plow for twelve hours a day like they were designed for. :D There are only two ways to solve it that I know of. Adjust the float or not let it bother you. I prefer the latter :lol:

Checking some of your other posts, you mention owning a breaking plow. I don't know if you're referring to a 193 single moldboard plow, a two-way 189 plow, or a 152 disc plow (mounts under the Cub), but all will allow you to work your Cub thoroughly. Even using your disc with added weight would be sufficient.

If you have a rural friend or neighbor who would let you disc or plow up a portion of ground for about an hour, that would really put your Cub to the test and perhaps clear up the smoke issue. Use the Sea Foam as directed while working your tractor. If after that the smoke doesn't clear up (or substantially reduce), then you can look at other measures.

We're all interested in this. Keep us posted on your progress. :coffee:

Thanks,

It is a 152 disc. I have two garden spots that I plan to disc so that
should give plenty of running time to test. Someone told me to remove
the plugs and soak each cylinder in some MMO. What do you think????
I have never used the stuff.

Possibly your Dr. or maybe local mechanic could prescribe the nicotine patch to help it quit smoking. :-:-):
If you are not part of the solution,
you are part of the problem!!!

If it has the breather tube on it that goes from the front of the block to the top of the air cleaner tube, check it to see if it is stopped up

Thanks Didymus,

That was the first thing I tried. By the way it was stopped up.
Thanks for the suggestion!!

I can't figure this thing out! Sometimes it smokes worse than others. Seems to always smoke under load but
will stop smoking so bad after running a while. It shows almost no smoke when first started and for a few minutes.
I guess I will just run it and see.

What weight and type of motor oil are you using in the engine?

Just a thought, using a heavier weight oil, such as straight 30W, might reduce the smoke.
I have an excuse. CRS.

This won't be popular, but several yeas ago I bought a smoking tractor….I had previously owned an old Lincoln with 365,000 miles on it and it smoked….I bought a bottle of " NO SMOKE " from walmart and it worked on the Lincoln so I tried it on the Cub…I guess that was about 3-4 years ago and I add a little ( according to directions) with each oil change…Once in awhile it will lightly smoke when started but after that its fine….I have done a lot of work with that particular tractor( spraying and grading) and no problems so far…. I've been running 20/50 in it for years…I have a spare engine on the stand that if I ever get it done might go in it….And might not... :lol: Dave….Short answer, It changes the viscosity of the oil……(heavier)

Hi All,

After running the cub hard several times and changing the gas and oil again it's smoking as bad as before. Still blowing a little oil out of the exhaust
pipe in the form of spots. I think I'm going to remove the head and have a look. Any suggestions of what I should look for?
Thanks in advance for any help !!

Did you do a compression check? Are there issues with less power than you are use to? I had the same thing happen to me after using sea foam. I went back to the auto parts store and got an additive for the smoking. It is worth $20-30 of more oil additive/ treatments before you get into pulling the hood, the head and pan and taking the tractor out of service this time of year.
When you only have 9 horsepower you need to know the names of all of the ponies!

Make it smoke the whole pack to teach it a lesson. :{_}:

In all seriousness... Unless you're fouling plugs, I'd just run it for a while and see what happens.
