I just bought a nice 750dp on Ebay(4779-2) but when I got it, I noticed that it didn't have 4 corner idle adjustments. I thought all dp carbs were 4 corner idle,or am I wrong?
Is is ok that it's not 4 corner? What are the advantages and how hard would it be to convert, if I wanted to?

There are details/kits on the net for that set up, you want a different rear block for starters.I have a 2 corner with different intakes and cams used with no problem at all.

I'd say most are not, until recently. Also I wouldnt sweat it, unless you have a seriously finicky car at idle, the primaries usually work just fine. Sometimes easier to adjust IMHO

That is a true statement, IFR and air bleeds determine the air mixture front and back, just the fronts have an adjustment of that mix

Not sure which comment you are replying to, but ALL Holleys, all, every 4 barrel, has primary and secondary idle circuits, however the 4 corner idle, has ADJUSTMENT on all 4 versus just 2

Its not there just for idle, its also there to keep fuel moving when you arent using the secondaries, assuming someone very much UNLIKE us may let the secondary fuel go stale and or varnish by not opening them up.
