750 the 4150 series.
And the thing that really bugs me about this carb is the idle adjustment on the secondaries.....which is impossible to get to unless you purchase the part to make adjustment easier....which I dont understand why they didnt put that on anyway. I actually put a piece of cardboard under the secondary just to open the butterflies just a bit so that I could lower the primaries to make sure I wasnt uncovering those transfer slots. I think I have that done now.....so tomorrow I plan to play with the mixture screws with the vacuum gage attached and see if I can improve the pressure and improve the idle.
