Holley carb ID

Summit sells that very same style carb under their name so I bet you can get parts from them for it. Here's a link to the Summit carbs.

what is it that would make you think this is the same? i'm not doubting you, just would like to know how to tell. everything looks real similar except for the electric choke. my 4010 is a manual choke..
