Tractor

I am so irritated but I am also excited about the idea of working on my tractor.
It is finally started, (battery charged) but It sputters. It runs a few seconds then dies. the engine will race then just die. When I began the chore of replacing the gas line and filter, It was doing the same thing. I assumed it was because of gas flow, So now what do I do?
David helped me as much as he could yesterday. Finally I decided I can do this, I took the carburetor cover off and checked it out, (as much as you can without removing the entire thing).
It is pretty dirty.
I am assuming it is the dirt that is making it so stubborn.
I called my Son, He laughed when I said, I can rebuild it if necessary, (He knows I can). For information Charles is the one we all call for mechanical problems.
Charles suggestion, "Go to Napa and buy a spray to clean the carburetor". Huh??? I did not know such an item existed.
The problem sounds like something in the line or poor contact. (I think)
But then I am always thinking.
So today that is my chore, shop, come home work on the tractor more and if all else fails. SCREAM!!!!
The grass is getting pretty high in the field and I NEED to mow. Lord knows we can't afford to hire someone to mow for us. That would be a big waste with the tractor setting there waiting for a knowledgeable hand and mind.
Obviously not mine.
