[Farmall] M carburetor seepage

[Gordon Williamson]

   How does the tractor run?  If it runs very well then I would make it a
point to close the fuel line valve at the strainer. Most Farmall owners
always do this at shutdown.
   You have a float valve that is not shutting off the fuel. Either the
needle is not seating  (dirty/worn) or the float is misadjusted or has a
hole in it. Start by insuring there is no hole in float, or fluid in it.
Then adjust it spot on. Then clean and reseat the needle valve. Give it a
very slight tap on needle when it is in the seat.
   I'd also drain about 1 pint of fuel into a glass jar, from the fuel line
where it connects to the carb. Let it sit a few hours and see  what is in
the bottom of the glass.

Subject: [Farmall] M carburetor seepage

The carburetor on this M I just bought was dripping way too much, like a
half a cup a day.   Last night I cleaned all the gunk off and could see that
gasoline was leaking from where the fuel line connects to the carburetor, so
I just tightened that brass fitting and it stopped the main leak.  But after
an hour or so I noticed that gas was very slowly seeping out along the joint
between the upper and lower halves of the carburetor, and a bit more seeping
out from that little thing at the bottom (a drain?).  By this morning, the
fuel-line fitting is still dry but the whole body of the carburetor is once
again wet-looking from the other seepages, and the occasional drop of
gasoline drips off.  Not a huge deal but I'd sure rather it didn't leak
anything, mostly to keep the smell of gasoline down.

So I guess I need a carb kit.  Any recommendations on which ones to get or
not get?  Useful tips for a first-timer?

Thanks much--
