[ScarletNape]

I plan on jumping right in and getting some help from you experts out there. I became a full fledged member last night and read that yall like pictures so here they come! Thank in advance.

Who thinks this carb needs to be rebuilt?? Hahaha

There is a small hole located on the very bottom of the clutch housing near the hand hole cover. I have researched the heck out of it and can find nothing. It is threaded. Any help would be great!

I need to know what to plug these threaded holes with. Some seem to have some silicon as a patch job.

The holes in the bottom photo came from the factory with cork in them.

Okay, thanks! Do you know of any good alternatives to the factory cork to get them plugged back up again?

Cork is probably your best solution if you ever want to use the holes. I think it would be the easiest to remove. You can try your local hardware store or just order them from TM Tractor who is a site sponsor. http://www.tmtractor.com/new/gr/576fp.htm

I don't know if carb needs a rebuild or not but it could use a cleaning and a new fuel line. See how to section to make fuel line.

Don't know about hole be hand hole.

1. Have no idea on the carb. Can't tell if it needs a rebuild from the picture. If the tractor runs well, leave it alone.

2. No idea what that hole is. Never noticed it on either of my Cubs. If it was factory I would expect some amount of extra material there, but that is drilled right through the thin part of the cast and has very little strength.

3. You can get new corks online or at a craft store. You can also use bolts of the correct size. 5/8" x 1-1/2" long coarse thread bolts fit. It is not wholly necessary to plug these holes, though. If oil is leaking OUT, you have a major issue that needs to be addressed. The cavity behind these holes should be "dry."

Thanks All,

The carb picture did not show what I was getting at the. The fuel bowl gasket is half way gone and it likes to leak fuel pretty steadily. I have a gasket set on the way and I just ordered some corks for the other holes.

Thanks Eugene,

Would you say that is a good indicator that I need to replace the tranny seal? I really don't want to have to do that at the moment because it seems to be quite the chore! But there is a pretty large wet grease slick on my belly mower.

Bad front transmission seal would likely be dripping from the hand hole cover. Bad rear engine seal would be dripping from the flywheel cover. Where is your drip coming from, if you have one?

[Barnyard]

When you remove the top of the carb make sure you lift straight up. There is an idle tube inside that extends from the top and into the bottom. If you aren't careful you can break that tube. While you have it apart, set the top on without the gasket to make sure the top is not warped.

I am going to get a new picture in the day light. It might just be hydro fluid leaking down on everything making it look like I have multiple leaks. The only visible drips I can see is coming from the carb. Thanks for the help.

Thanks for the tip!

The holes in the middle picture are attachment bolt holes, and unless someone drilled them deeper, should not leak anything. If you want to plug then to protect the threads, a set of bolts slathered with neversieze would suffice.

If that is true then someone drilled them out. Most of the holes were at least 4 inches deep.

Alright fellas, who is the leaky culprit? I have decided that while I am changing the oil I am going to replace the pan gasket as well. Couldn't hurt right?
