Slant Six has No power. will not accelerate

I had the same problem with my 63 valiant 225 slant six, 1920 holley 1 brrl. When I first bought the car the bowl gasket was leaking. When I went to replace it I noticed that they gobbed on silicone sealer to the gasket. Some strans of silicone were starting to come loose. I cleaned all that i saw, but of coourse the little tiny piece that i must have missed found its way in the metering block and clogged it. This time I took everything apart and gave it a good cleaning (i hope). Put it all back together and the car runs great!!
