Is one aluminum and one steel? If so I think the steel goes in the pump discharge hole under the pump discharge spring and held in by the "T" shaped spring guide. The aluminum would go in the bottom of the pump plunger well under the pump return spring.

Big ball DOES NOT go in the bottom of the pump well.

And if you put it in there mistakenly, good luck in getting it out if it wedges in there.

One should be aluminum and one steel.

Aluminum goes in the accelerator pump well and the steel one in the hole below the venturi.

I have some really old rebuild kits and they are definitely aluminum and steel.

If you make a mistake and put the large ball in the accelerator pump well, I have posted a method of removing it. It becomes wedged in the too-small hole and is difficult to remove, but it CAN be done.

Dick - I use a modified version of your method by adding a grease zert to the tapered fitting and using a grease gun. The grease will hold the ball so it doesn't hit you in the forehead

One needs to have the casting in a vise with the access plug covered when this is done.

Heat will then melt the grease, and it can be washed out successfully.

Agree with Dick B and Jon H about the locations of the check balls

In a really bad situation with the ball stuck in the pump well I have drilled a small hole from the bottom side of the fuel bowl and the drove the ball out.

Then I peaned over the zinc material of the fuel bowl so that the drilled hole was sealed again. Not a perfect fix for a 100% restoration but has worked well for several enthusiasts on a budget with no money for newer castings.

Thanks again EV1. The kit did have an aluminum smaller check ball.
