needle and seat for a holley 1050

[joeq66]

I have a e85 1050 dominator carb and its starting to flood slightly.I was going to replace the needle and seats but after looking at mine I think they are .170s.I had the carb done by prosystem and the work order said .170.The problem im having is finding a .170 needle and seat.I see a lot of the ss .150 and was wondering if they will flow enough for e85.Any opinions would be appreciated.Im right around 650 hp..thanks

DEPENDS ON YOUR APPLICATION .IF THE AREA OF THE REGULATOR FLOWS LESS THAN AREA OF THE THE TWO .150 AT THERE REPRESENTED PSI THEN YOU WONT SEE A DIFFERENCE .170 WILL RESPOND QUICKER TO FLOAT DROP AND KEEP UP WITH A MAJOR DEMAND .
HAVE YOU TRIED A VACUUM REGULATOR ?
