I don't even remember where I got this carb. but decided to rebuild it and have run into a couple of issues.
In the attached photo the #1 issue is that there was only a needle that I saw that came out of the hole circled. If there was anything else i didn't see it. There were two ball that came with the kit. A larger one which forces the needle above the rim of the body and a smaller one forces the needle even with the top of the rim leaving no room for a retainer. Maybe there isn't supposed to be a ball in there ?? I haven't even yet seen where those two balls go.
One other thing that threw me off is that a few of the kit parts are of a different design from what looks to be original parts. But I eventually figured those out.

Carb. Model is a YF 788S. 1950-52

I'm sure there will be more questions to come. ohwell
