I did not notice that. I'm still learning about all these little carbs. 4 1 bbl carbs with a little cam might run pretty good. Damn sure look cool. What's the motor specs? I'm getting ready to build a 50 merc for my coupe.
I made them , screen door screen , fine scotch brite pad , course wire to fit top of carb to keep everything in place. Scoop holds pad and screen in place. Keeps some dirt out. And big birds. Running them like that since 1990s
