I had a similar problem that drove me nuts for months, I would run the car then suddenly it would bog down and stall. The car would also start and run fine then run really rough, when I looked down the secondaries, I could see fuel pouring out of secondary squirters.

My car has a Holley 1850 with non-adjustable floats so I removed the secondary bowl and inspected and cleaned the needle valve and housing, everything looked good so I reassembled the carburetor. Many times, I thought I fixed the problem but it would always come back. I eventually bought a new $13.00 secondary valve and housing, this fixed the problem.
