FROM Bamairon

i have a sb 350 camel hump heads,small racing cam 2500 stall,E750 double pumper carb when i hit the gas it keeps flooding at take off it smooths out quickly but this stall is driving ne nuts have tried adjusting but 2 no avail can somebody help me.

i think the carb is way too big for your application.

A 600 cfm will do nicely, even a 500 will work well with a mild race cam. While I know some people have or are running a 750 and doing it well, it really is too large for a 350. JMO.

He's probably running too large jets in the primary and a 50 cc pump and I agree with both of you, a 750 DP is too large for a mild 350.

What I'm hearing is flooding equals bogging. I remember the post also. Is it really flooding or is it bogging. I can have that 750 mounted to your toilet or your kids bicycle and it will perform. So, I am bewildered on whether it's a bog or is it truly flooding.......hhhmmmm.....

I am kinda with you on that Nitro. Never ran a 750 on a 350 or so cube motor, but always found that size, be it Holley or Edelbrock, etc. worked the best on a 390 FE Ford. Street wise and strip wise.

With the right cam, heads and tune, a 750 will work just fine on a fairly robust 350 (400+ hp). It's just tough to make it work on a mild 350.

I doubt if it's flooding. I'm guessing it's just getting a big gulp of air and bogging until the R's come up.

I wonder what he's adjusting?

Jack, I gotta apologize to all, I just reread Mooneye's post. The guy is running a 750 DOUBLE PUMPER with a small cam and a 2500 stall speed converter.

Man, that's just wrong. No wonder he's getting the flooding feeling.

Duane, no need for apologies. Nobody came here and described the problem as a bog or flooding. I want to hear which it is. Everybody assumes what the correction factor is. Nope, let's find out what the real description of the problem is.

I guess we need to know how many RPM'S he is turning so we can at least come close on the carb size.
I would guess it is a acc. pump problem.
Maybe a squirter size or maybe a acc. cam size or location would help.
Is he "leaving" at 2,500 rpm's or is he "leaving" off idle?

thanks all,went with smaller carb as suggested,running like a top.
