I fitted the holley and manifold today to the 173 and its all set up decently ok. Turned the car onto on to get the electric fuel pump to fill the fuel filter and I was watching it carefully, then the little hole at the top of the carby started pissing out fuel everywhere all all over the carby and manifold. Turned off the key and let it sit for a while... tried to start it quickly and nothing, perhaps flooded? Then after leaving it off, fuel kept draining through the carby into the manifold... there is like 200ml of petrol in the manifold. I removed the plugs and the carby from the manifold also. Tried to soak up as much fuel as I could, and left a lint free clean rag in the manifold to soak up what was left. Hopefully whatever is in the cylinders will evaporate overnight through the spark plug holes. The guy who I bought it from said it was completely reconditioned, and it seemed to have new gaskets and everything... manifold was new and it had a new carby-manifold gasket. He said he never put fuel through it yet or anything, but had it installed and set up ready to use. He has lots of cars and I'd say he knows his stuff... but I'll give him a call in the morning and ask him after I find out what you guys think because then I can have some idea if its me causing the problem, with perhaps... too much fuel pressure going into the carby or something? The stromberg was fine though with that same fuel pump.
