Re: Dp vs. vacuum carbs

I tried one of those junk toilet bowls for almost a year.
I did nothing but remove it and install my Holley and went a full second quicker.
They basically work like the back half of a Q-jet. Big air doors on top attached to a cam through linkage, the cam is what meters the fuel. It comes with three cams, 1,2,and 3, 1 being the leanest, 3 the richest. It uses a double check ball instead of a needle and seat. The street version has an adjustable idle circuit.
They are very forgiving, you will never get a bog out of one. But they don't make any power either.
