Dad managed to get the ball out of the part in question... he left it in the carburetor cleaner bucket for two days and it rolled right out. I guess it was gunked up good.

However, as with all things Stovebolt, he has encountered another issue.

Using the above diagram... the following parts are missing, the hole was filled up with 'goop' as dad called it. I wasn't there when he discovered this.

The parts missing:

spring 3.823

screw 3.822

Those parts are not in the rebuild kit, as I imagine that they are supposed to be reused.

Anyone have an idea of how to acquire these parts... I would imagine that they would have to be used?

Wrenchbender, thanks for the offer.
