[AJD] JD 40 Carb

[Duane Larson]

LeRoy,
That sounds strange - I've built a bunch of TSX carburetors and rarely have
a problem screwing the seat in place.  I wonder if you were given a wrong
kit, or it contains the wrong needle and seat.  Does the needle have a viton
(rubber) tip?  I don't recall a problem with needle size, but it is late and
I can look at my notes later today.

Another distinct possibility is the float is hanging on the cast body - that
is hard to see, make sure the float arms are symmetric as if they are bent
much they will drag and not cause the needle to seat.  Bruce was right - you
should be able to hear the float move up and down as you turn the carb.

about that little O ring that seat under it.  You know I bought 2 carb sets
for each JD 40 I have.  The seats seems to be slightly taller.  I had to go
out and buy a screw driver that was wider but still was a tad short at the
blade.  I got it in both carbs almost 3 quarters in before I really had to
apply pressure.  I had to give up on the JD 40S it just wouldn't go in but I
was able to get it in the 40W.  I did eventually hook up the gas without the
body to see if it shut off.  Thats when I saw it leak around the seat, a
little more pressure to tighten it seem to work.  But once I get it together
it floods.  Not sure how far I can bend the floats down before I don't have
enough gas in the bowl.  The kits said JD40 but maybe there marked wrong.  I
lostthe original needle or I would have put that one back.  One thing I
noticed is that the new needle doesn't fit in the old seat its bigger.  Is
that right?
