Many Craftsman mowers use Briggs and Stratton engines. Go to the B & S site and look up an exploded view of the engine. It should show where the springs go. Follow the diagram and please be very careful.

I took apart to 510 to clean I have little spring & ball bearing where does it go. It idles on full throttle

Hello Kerry McKinney,

I'm sure "510" means something to you...
(You really need help? Full nomenclature works best).
((I have no IDEA what carburetor YOU have here))...

I know (once upon a time) there was a DATSUN
by that name "510"... You posted a comment on other gardening tools so I suspect that is your area of concern.. To pull
Your fuel like out of your tank you can use forceps our fashion a wire or paper clip into a hook and GENTLY pull up the fuel line...

(even a hemostat might work)...

The "ball & spring" WERE a CHECK VALVE until
you misplaced them... blow into the end of the fuel line and fine where it come out of that carburetor body... that is where the ball goes in first, spring behind... which will keep the gas from flowing freely into the carb... but allow fuel when vacuumed from the engine...

CARB =====//////O>=============== TANK
'.... FUEL-LINE ......'

You SHOULD try to find a REBUILD KIT on-line
because everybody dreads seeing THAT SPRING flying
out of something the open... and the INSTRUCTIONS in the "KIT" will usually help with that...

a drop of red food dye gently put into the tank end of the fuel line... and GENTLY ADVANCED with a syringe should help you find that BALL-SEAT... Use come CARB-CLEANER to get it out before re-assembly. If you must use gasket seal... use only the recommended amount of a big NAME like Permatex..

Sloppy re-assembly with silicone sealant is the biggest
cause of AMATEUR small carburetor "CLEANING"
troubles (well that and looking... isn't cleaning).

CLEANING means using a solution made for the purpose to DISSOLVE dried dirt and petroleum products for the carburetor body (follow manufacturers instructions (not more petroleum)).

I recommend Berryman's Carb & choke cleaner (below)

Finally as to "idle" at "FULL THROTTLE"
(nah... Can't be connected )

Re-connect that throttle linkage... properly.

How to adjust automatic choke

Procedure #1-
  1. Be sure the hook on the bimetallic spring contacts the choke shaft lever.
  2. Install the cover and retainer and lightly tighten the screws.
  3. Turn the ceramic element to align the mark on it with the middle mark on the housing.
~~~ Procedure #2-
  1. The engine must be cold to make this adjustment.
  2. Remove the air cleaner.
  3. Find the automatic choke. It's the round thing on the upper right-hand of the carburetor. There is a wire coming to it from the positive side of the coil.
  4. Note: The automatic choke is a round ceramic thing with the heating element wound inside of it. (The ceramic part may be covered with metal so that it looks just like the rest of the carburetor.) The choke is held in position by a triangular ring clamp and three screws so it can be loosened and rotated for adjustment.
  5. Pull the throttle arm on the left side of the carburetor down to free the little step arm (cam) that the screw at the top of the throttle lever rests on.
  6. Note: This stepped "cam" is connected to the butterfly valve inside the throat of the carburetor by a shaft that extends all the way into the automatic choke. With the engine cold, the butterfly valve should be closed. As the engine warms up, the coil inside the automatic choke uncoils, opens the butterfly valve, and moves the cam to reduce the idle speed.
  7. Release the throttle arm so that the return spring snaps it back. The little screw at the top of the throttle arm (again, with the engine cold) should now rest on the top step of the stepped cam. This sets the hi-idle, which is needed together with the choke on a cold engine to provide sufficient idle speed to keep the engine running until it warms up fully.
  8. Loosen the three screws on the right side that hold the choke in place.
  9. Keep your eye on the butterfly valve in the carburetor throat.
  10. Turn the choke element clockwise (viewed from the right) until the butterfly is standing straight up, then turn the choke counterclockwise (viewed from the right) until the choke butterfly fully closes (barely -- not too tightly), then tighten the three screws that hold the choke in place.
  11. Note: This is important; the automatic choke may be assembled wrong and not catching the hook on the coil spring at all.
  12. Start the engine with the air cleaner off. As the engine warms up, make sure that the butterfly opens until it is standing straight up (full open) when the engine is fully warm. If it doesn't, readjust the choke until you get it right.
  13. Note: The engine is now warm, so you won't be able to adjust the choke per the foregoing. Note the position of the notch on the side of the choke relative to the three little ridges on the body of the carburetor. If the butterfly is too far closed with the engine warm, turn the choke clockwise just a bit to straighten it up. The notch on the choke should never be too far outside of the three ridges on the body of the carburetor. If you are not able to adjust the choke using these method, something may be sticking, or perhaps the coil spring inside the canister is broken, or perhaps the wire has fallen off of the contact on the canister so that it is not getting power from the battery properly.

There is an idle control spring that fits from the loop in the throttle linkage to the plate at the front of the motor. There may be one other spring if it has an auto choke system that fits from the choke lever to the flywheel cover

I have a lawn vacuum which uses a B&S 129882-1936-d1 engine. I can start it on one pull, but then it quickly dies. I've checked and have airtight seal. WHat I can see is that the throttle cable...

I'm surprised you can't move the linkage yourself. The spring is attached to an arm that goes back under the cowling. That are has a blade on it the sits in the airflow of the motors cooling fan. As the motor runs faster the blade causes more tension on the spring and changes closes or opens the carburetor a little. The throttle cable and the fan set the position of the carburetor. Check to make sure the the blade up in the airpath has not somehow gotten jammed. Also the choke setting can cause the problem you describe. Make sure it's linkage is not binding somehow...
