This is the first time I have seen the inside of one of those VERY antique carburetors. Are they much different from Ole’s Row Boat Motors? . . . 😐
Other than the materials the design is nearly identical, the old RBM’s are made from bronze and the Elto’s from aluminum…for the most part all of them that I have ever seen.
I am not sure on the Model K RBM if it has an aluminum mixer or bronze…
