Another possibility is that the wrong gasket or a defective gasket is in
there. Fuel should definitely *not* leak into the venturi from the float
bowl. It is not unheard of for a new needle and seat assembly to be
defective either.

I have had the exact same trouble with the last kit I put in. The float
needle and seat were bad. The store warrantied them.

The idle tubes are those two long brass tubes that hang down. They are
real sneaky for plugging up. I can just remove the choke plate and then
the two screws holding the venturi in and lift and twist the venturi
around so it slips out without removing the whole top of the carb for
cleaning. You have to blow through the tubes to make sure they are
clear. The tubes 'can' fall out too.

As a note, the solvent will 'not' clear blocked tubes. They do need to
be reamed out with a piece of wire at the least, and oversized with a
welding torch tip drill or file to help keep the suckers clear. I think
half the dirt that gets in them comes from that U shaped chunk of gas
line between the filter and carb. It needs serious cleaning on most.

Here is a link on the tubes:
http://www.off-road.com/jeep/tech/engine/carter.html

Don't forget that the gas filter has to be in right side up.... It has
2 outlets. The center one goes to the carb and the top one goes to the
return line. If the return line isn't up top, gas can syphon back to
the tank when it sits.

Hey....

Took the idle tubes out like you suggested.
They were clean
double checked everything and found that the idiot that "overhauled " it
before swapped the gaskets.
He put the lower gasket between the idle tube cover and the idle tube gasket
under the venturi cluster causing it to leave a little gap between the idle
tube cover and venturi cluster where the gas dripped out.

Off course the last idiot that worked on it just peeled the old gaskets off
and also put the new 1's in wrong
( oh wait , that was me...... :-) )

after starting it and cleaning the gas out off the manifold I started it
again after an hour and it fired right up


Thanks yall for the tips
