[AJD] More JD 40 Carb and other stuff

[Don Shehi]

Duane

Have you rebuilt the TSX688 carb?  I have one my recently purchased 430U.
This one has set for several years, a lot of rust from condensation. The
little work I have done is to remove the top.  Using rust eater I have one
of the shafts free. What should I be aware of?  Should I send it off and
have it rebuilt?

Thanks

LeRoy,
I'm beginning to think you have the wrong kit.  If it is a TISCO kit, the
box should say BK39V, or if it is a Zenith kit, it should be K7515.  I will
measure my seats this morning and see what sizes/threads they are.  It
sounds like you also have the float for smaller TSX carbs.  I will try to
check the difference and give you a measurement.

I rebuild TSX530 carbs regularly and have no problem with the BK39V kits.  I
haven't bought any for a year or so (I buy several when I get them), and it
is possible they have messed something up with the recent buyouts of TISCO.
Regards,
Duane

kits so today I stopped for a tap to clean out the carb hole that the seat
is placed.  For kicks I stopped by the fine thread nuts and picked out a 3/8
X 24. I tried it on the old seat and it screwed on without issue.  I then
tried it on the new kit seat and I couldn't get it an 1/8 on, just wouldn't
go.  To me its the seat, something is wrong with it.  Bought the tap anyway
and it didn't make a difference.

bit shorter than the original hence I don't have much adjustment since the
bending the float down will start them rubbing on the inner sides.  I did
notice that the fuel bowl was loose and I tighten that.  Is there a good
replacement for the float?

mean if I start it out with a little gas it pops along.  If I give it more
throttle it runs faster but when I decrease the throttle it doesn't respond,
stays running like it wsa at the previous position.  What do I look at?
