I just got my first Cub Cadet Original the other day and was working on it this weekend trying to get it started.

I know I can get it to start if I can get past my carb troubles.

It has a Carter Model N carb that is gummed up with sticky stuff from old fuel. I was able to get the tank cleaned out and fuel running from the sight bowl thru the line but nothing is getting in the carb, I assume it is plugged up from this sticky stuff but not sure what to do now.

Should I take the carb off and soak it in something?

I took the bowl off the bottom of the carb and sleaned all the nasty out of it already.

 

The second problem is that the metal fuel line from the sight bowl to the carb is now leaking on both ends of the line.  It has was appears to be rubber seals on both ends that are rotted.

 

Is there a better way to run the fuel line than using this little metal one??

 

I will listen to any suggestions you guys have.

 

Pictures of how you have your fuel system would help as well.

 

Here are some pictures of what mine has right now.

Needle and seat at the fuel inlet is plugged. Take it off and blow through all of the little orifices with carb cleaner.

You could replace the line with new copper line, nuts and sleeves. Hardware stores or auto parts store should have the things you need. Take the old with you for sizing. Carb should be taken off and put in cleaner. New needle and seat put in. Just my two cents worth.Noel

Ok guys, thanks for the advise.

 

Noel, as for the rubber seals that are behind the nuts and sleeves, where would I find those at??

 

Should I take the carb all the way apart to clean it or just soak it good??

Take it apart is the best way. I would say the auto store for the rubber seals. May not need rubber seals if you put all new line, nuts and sleeves. Noel

Not sure about that. I would start at your local small engine shop and check e bay. U tube has information too. Noel

I have the Carter carburetor kit if you want it.  It is very cheap and very simple, $13. 

 

I would replace the needle and seat and all the gaskets.  Take it off the engine and clean it up by hand to the best of your abilities.  Get a piece of fine copper wire and run it into all the holes.  Get a gallon of carburetor cleaner which will last you for a long time, and soak it for 1/2 hour.  Take it out and rinse it in a good aerosol cleaner, like 2+2.  After that, put it back together and adjust it back to specs.  It will run like a champ. 

 

That copper fuel line should have only a compression nut and a little ferrule in it.  The rubber seal was probably added by a concerned owner.  I would replace it with new line, and it will not leak.
