Hi, I tried to rebuild my 4100 on my 58 Edsel and all was good except my secondaries were siezed. I soaked the piviot in PB Blast and was able to free them partially but by the next day they were siezed again. Anyone know a good cleaner I can soak the carb in to free it up permanently, or do I need to pull them out and replace it? Thanks!

Don't give up so soon. Soak it overnight, wiggle it some, soak it overnight again, wiggle some, for as long as it takes. If it wiggled once, it will wiggle more after soaking with the right stuff, long enough. I once saved a rare AFB like this, it took weeks, but it ran good when it was cleaned up.

Try a 50-50 mix of acetone and atf ( Automatic trans. fluid.) it works really well at loosening up seized parts. then follow Ole Don's advice. it may just take a little time and patience.
