Help

				Just looking for a bit of help with my Lancia Fulvia 1300 GTE. It had been standing for many years and the engine was seized.
I have just rebuilt the engine with new pistons etc. I have plenty of experience with Alfa Romeo engines but this is my first Lancia. I followed very carefully all the recommendations with regard to torqeuing down the head etc etc etc and used a factory workshop manual during the rebuild. BUT I cannot get it running. I know the valve timing is correct because the little marks on the camshafts line up with the marks on the rocker mountings when the crankshaft is at TDC no 1 cylinder (0 mark). I know that it is sparking on all 4 plugs. Battery is new and distributor and rotor arm could do with being replaced but I have cleaned them up and there are definitely sparks on all 4 plugs. I have cleaned up and dressed the points. I set the timing with a light bulb and I know that the spark for no 1 cylinder is occurring at 8 degrees before TDC because I connected a strobe to no 1 cylinder and it illuminates the 8 mark when the engine is being cranked.
I stripped and cleaned the carbs before reassembly. I know that the fuel pump is working properly becuase it is filling up the float chambers and the fuel filter bowl. I can see plenty of fuel being squirted out of the accelerator pump when my assistant pumps the throttle.
It makes banging (almost backfiring noises) when you crank the engine over with the throttle pedal closed. If you pump the throttle or try the choke it stops banging and backfiring and nothing happens. To me this suggests that it is too rich. It has the Solex carbs and I stripped and cleaned the jets in the main body and the accelerator pump mechanism. I blew air through them. The car had been standing for some 15 years...are there some O rings in the carbs that need replaced that might lead to the above problem...any suggestions gratefully appreciated. My Alfas always burst into life immediately after an engine rebuild!!
