Saw a review that says it fits there 2300 2 kegs exactly. So I bought it. Because there is no electric choke for the 2300 2 barrel that Holly makes. Although they have the opportunity to come with one. The pressure screw hits the body. There's nothing I can do to make it work. It just doesn't fit this carburetor. Another punch to Holly's teeth. It NEVER ends with carbs. FYI on the quick fuel pick I added spacers and got it to work. It wasn't even possible with what Holly sent me. If you have a 2300 2 barrel, go for the quick fill option and use some sort of spacers cut from a tiny metal tube.
