OK here is the story.
I work at Major Corvette shop in Riverside Ca.The Car came in with a carb and high rise manifold on a 1960 283 / Turbo 350 and all the original 57 FI parts in a box - everything from Manifold to distributor.
I went through every FI item - Replaced all gaskets, seals, and diaphragms. Made sure that all injectors and lines were clean and clear.
The car actually runs quite well until you shut it down. Upon restart it is always flooded and needs 1/2 throttle to start and clear out. At times the cylinders are so full of gas that it will Hydro lock damn near. I removed the upper manifold and any intake valves that were shut have that port full of gas.
Question is --- What id used as say a check valve to keep the system from draining into the cylinders? Is it the spring tension on the spill valve that would shut the fuel off? Could i have damaged the spider when I blew air and carb spray through the spider? Is there a check valve in the Fuel spider?
I have done several others with no problems on restart - this car is got me baffled.
