[Farmall] Super A Carb Leak

[Barney Van De Weert]

The needle and seat control the level of gas in the carb bowl. If it over flows 
the gas drains out of the hole by the choke. The float, needle and seat are 
probably still suspect, the fact it leaks after you run it indicates the needle 
is not seating correctly or the float is sticking and not pushing the needle 
into the seat. 


Also if there is any dirt at all coming from the tank, it can cause them to leak 
as well. Make sure the fuel bowl is clean and has a screen installed 
correctly in it.

I have had brand new needles and seats that still leaked.

Hello,

Thank you for all the imput.  The carb leaks from the drain in the choke 
housing.  First off, if you have had the same problem and figured a  way 
to fix it, I really would like to know how you did it!

Here's a clue that maybe someone more experienced than me could 
decipher.  The carb, once I rebuild it, doesn't leak.  In fact, I left 
the gas on just to check, and two hours later it still didn't leak.  But 
once I run the engine, it leaks.  What would cause this?  The float, 
though it is brand new, I tested yesterday, and it is sound.  The 
needle/ seat I tested, and replaced.

Would this fact of when the carb leaks make a difference in what the 
problem is?

Thanks,
Ben Wagner
