Lectron Billetron mini to the rescue!
Looks like a cool carburetor. I'm not familiar with that model but it looks like a flat slide design from the photo? For those of us vintage racing in AHRMA I thought we were restricted to round slide carbs? Maybe somebody could clarify here
Flat slide yup, all I know is it starts first kick and runs just like it use to in 1973, heck I even got a wheelie out of it!
