The one problem I did have was with jetting. Unfortunately, according to Holley, the jets for those are no longer manufactured. But I did buy some smaller jets from a guy in California and drilled them out to approximately what I needed.
What you could do, since it's brass, is to solder them closed and then drill out to the diameter you need. Hardware stores have those miniscule exact-size drill bits.
How did you know that your jets were too large? Fuel fumes in the exhaust? Fouled plugs? I'm really curious, especially since I may have to do the same thing.
Did Holley say that there were no jets from other carburetors that would fit?
