How does the needle valve assembly all go together

Is the tool not broken at all?I know crazy question but at the shop ive seen that multiple times.
If thats not the case try this with no valve stem tool

try small needle nose pliers

Hello Johnnie Thomas,

If GASOLINE is allowed to STAND it can VARNISH things together!

Either you have a stuck (or obstructed) valve seat...
(on the business end of your float)...

or the float ITSELF no longer floats
(freely: a malformed gasket can also obstruct free motion).

In principle the float bowl acts exactly like a "TOILET TANK"

When the fuel DROPs below the IDEAL level, the float (also drops) & the pressure released from the fill valve
(typically a needle &seat)...

Most carburetor kits include a new needle valve...
precisely because it is vital to the function.

Sort of a full CARB Rebuild... try cleaning the inside of the fuel bowl with Berryman B12.

Hope this helps.

The blend door actuated by solenoids may not be working correctly causing a/c cool air to come out of the windshield vents, rather than the regular front vents.

have the carb rechecked that the float is correctly set and valve is not worn or debris and fuel pressure between 7 to 10 lbs

An easy way is to remove the air cleaner off the carb, and give the top of the carb a couple sharp taps with a small hammer or a heavy screwdriver.. sometimes you can simply loosen the needle valve and float up this way.
You may need to take the top of the carb off. The float and needle valve work together to stop the flow of fuel into the carb. You want to check to see if the float is not full of fuel.. if it is , then it's got a leak and should be replaced... spray the needle valve and seat with carb cleaner spray to remove any build up.. And as long as the carb bowl is exposed, clean the basin out as well.

if fuel is not getting into the venturi of the carberettor, the top needs to be removed and look at the needle and seat assembly to determine whether or not the valve itself is sticking or there is something caught in the way. the needle and seat assembly will be a little brass piece right near the fuel inlet and will have a little rocket looking device which closes and opens the inlet as neccessary. happy holidays

The float needle valve and seat inside the carburetor float bowl needs replacing or has debris trapped in the seat. If the valve does not seat completely it will allow all the fuel in the bowl to flow into the cylinder. The valve stops the flow of fuel once the bowl is full. When it is not seating properly the fuel will continue to flow. This is not a good thing as the fuel will enter the crankcase and mix with the oil. This will eventually damage the engine bearings. You can purchase a needle valve and seat assembly to repair it. Here is what a typical unit looks like.

Where is the PVC valve? Standing in Front of the car it is on the left side of the air plenum. Unscrew the oil filler tube and remove the plastic engine cover. There is a sensor on the left side of the plenum. This sensor senses when the PVC valve is open/closed. Don't bother disconnecting the connector or the piece the connector plugs into. Simply twist the whole plastic assembly clockwise = yes clockwise while pressing downward to release the assembly. There is a spring underneath so don't let it pop up. With the assembly out of the way grab the PVC valve with a pair of needle nose pliers, wriggle the valve out. If the o-ring is ok put it on the new PVC valve. Drop the valve in place making sure it seats on the o-ring. Look at the bottom of the assembly to see how the slots line up with the tabs. Slip the slots down over the tabs compressing the spring and twist counter-clockwise. Replace the plastic engine cover, Done!

since the 4.2L is a push rod engine, you have the 4.6L or 5.4L which the valve train system is the same. The lifter can be removed without removing the camshaft by using two special tools that can be purchased from any tool house that sells special tools in your area. Tool 1 is a spacer to prevent the valve from traveling too far (damage to seal), Tool 2 is a valve spring compressor, that uses the camshaft as a fulcrum to depress the valve and spring enough to remove the rocker assembly, use a plastic pen to determine piston location before using the compressor tool, you want the piston approximately 1-2 inches below TDC, once the rocker assembly is removed the lifter can be pulled out the top. It is very improtant that the rockers and lifters be kept together by location (ie. exhaust number 3 rocker and lifter together) and installed back in thier original positions. If you can not get the special tools, then the only other option is to remove the cams. Hope this helps, let me know
