I had one back in the day, and only figured the damned thing out 10 years after I got rid of the car.
In short, Weber's are easy... just need some parts and a set of drill bits. There is then a blank jet that you drill with a starting jet... install, test, repeat with larger bit until done. The order that size jet. The jets are indexed with the bits.
Andy, these are actually Mikuni side draft carbs. Supposedly easier to work on.
The problem was when I first got them I bought a full on jet and nozzle kit and someone who supposedly knew these carbs suggested I set it up in a certain way assuming they would be small for the engine...they were basically maxed out on everything.
I was having bothersome issues like rich gas smelling exhaust, bad mileage even with a TH2004R, and a high idle both in gear and out of gear. Symptoms of too much carb. I researched a little bit and found that I was likely seeing close to 880 CFM, or 220 per barrel. Waaaaay too much for a SBC 405.
A shop owner I was already familiar with expressed confidence he could get them set up much better for the engine using the parts I still had so I dropped it off so he could tinker.
That leads us to the 5th of June, when the phone call I got was not a good one like I was hoping for.
