The idle circuit drillings are is different places; either gasket would be the wrong gasket for one or the other.
Got fuel pressure
Got fuel pressure it runs great and will idle for about 20 seconds then act's like it runs out of FUEL

Re: Carb help
Sorry about that mis-read your post, I thought you where having problems with the 750 and wanted to put a 950 base plate, not that you already had. Never done that swap sorry can't help you there but I know the Holley Competition 6109 and 8156 750's I believe use different base plates then 4779 750's so it may be the same deal and have something to do with the 4 corner idle circuits.capncruncher1965 wrote:Hey guys i have a 750 quick fuel carb and it works great thinking i needed a bigger carb i put a quick fuel 950 base plate on it try to make it a 830 cum now it runs about 20 seconds and cuts off maybe I put the wrong gasket on it any ideas

Re: Carb help
I would open the idle screws 3 or more turns and see if it helps.
