View Full Version : SU carb help

07-07-2014, 8:09 PM
I've never ran an SU but have heard that they're real easy to tune and that they preform great etc, so I bought one randomly off a dude for 8 bucks. Maybe I bought a lemon, or some carb off a fuckin tractor or something but I figured it was worth the 8 dollar gamble. Anyway, I'm not completely sure which model this is, or whether it's suitable for a harley, and I'm hoping someone can help me with figuring that out. There aren't any real markings on it except "su carburetor company Birmingham" and "AUC 6020 z". Here are a few pictures that may hopefully help.
Oh yea, there's a remote bowl and float that attaches to the bottom with a banjo bolt which makes me think it's not really great for a bike. But maybe I'm wrong.

Rivera Primo have been doing SUs for a very long time and should know what you need.

I'd give it a nice Pine-Sol bath and make it pretty. If no workee on HD it should make you a profit on Ebay.

Fun useless fact:
They'll still run with the slide cover removed but of course the slide won't lift since no vacuum.
