Holley carb questions

[67bondobronc]

I got my motor running and it will idle then all of a sudden it acts like I punched the gas and rev's high. So, I am thinking that the carb is loading. Also there is gas on top of my intake manifold that looks to be coming out of the carb somewhere on both sides, it looks to be coming out of a seam where the top and bottom of the carb connect. I installed new mounbting gaskets when I rebuilt the motor and it is on tight so I don't think it is coming out of the bottom that is connected to the spacer. So, I figure that I need to rebuild the carb. How do I tell what kind of Holley it is? It was on my 67 when i bought it and it ran ok but I have no idea what size or year or anything about it. Also, how hard is a carb rebuild? Thanks guys

Rebuilding a carb is not that hard. Just be organized in how you lay your parts out and soak/spray your parts then blow the little holes out with air to make sure everything is clean. Work on a large clean surface. There will be numbers on the front of the air horn on the right I believe that will Id the carb.

Thanks Jeepster, I went to the Holley site and was able to identify it, it is a 1850-2 600cfm. I went and bought the rebuild kit and have been studying the diagrams and there are only 156 parts

I will tackle it in the morning. Wish me luck on this one guys.

sounds like the float level was just a bit too high letting gas run out the boosters which would puddle on the butterflies and leak out the shaft. still its a good idea to rebuld it its much simpler than it looks and usually you dont need to remove the base plate of the carb but its only a few more screws.

I took 4 7/16" bolts about 1 1/2" long or so and bolted them to the 4 holes on the mounting base to make little legs for the body of the carb to "stand on". Makes life a little easier when working the carb on the bench.
