Edelbrock carb questions.
1. what are set-up springs?
2. is there anyone who makes a air/fuel monitor that i do not need to install?
3. Why does my car load up after i run her hard?
4. is there a book i can buy to walk me though setting up my carb?
I have the complete performer rpm kit in a 350 punched 60 over.
thanks for any help. :smash: :crazy:

As far as a book, they do have a lot of info on the web page that can be down loaded that's what I did for mine.
I think summit has a air/fuel monitor that can be stuck in the end of the exhaust for tuning.
Can you explain # 3 a little more?

#3 if i floor her after i let off she will act as if she has loaded up on fuel and i will have to rev her up to clear her out.
example: i was power braking her yesterday and when i got done and came to a stop she was not responding good till i reved her up to clear her out.
it will also happen whe i run her down the road and come to a stop but, only if i floor her.

Re: Edelbrock carb questions. (emsrescu)
You need to get an air/fuel mixture guage on it to see if it is rich or lean,it sounds like it is too rich.....suspect the power circuit or the float level....the edel carbs are very sensitive to fuel pressue,so check what pressure is.....i found that the pressure was fluctuating upwards and then overwhelming the floats,gave the same symptoms as yours....bogging at idle,stalling on overrun and rich as second stage opens but revved cleanly once past that transition point...john :chevy

Re: Edelbrock carb questions. (biltogo)
cool i will start with pressure checking. i just ordered the fuel line with filter, pressure guage, and fuel regulator. I have a stock pump for now. i will set the pressure for 6psi and see if that will help.

Re: Edelbrock carb questions. (emsrescu)
One thing you will need is the carb. calibration kit. it contain different size jet springs and etc. I think I paid around $60.00 for mine. Also if you have the 1406 carb. (1405 with electric choke) get the calibration kit for the 1405, it has jets designed more for performance.
The step up springs help with tuning how much gas is going in. They are very easy to change. Also the factory secondary jet aren't going be enough to rev past 4500, I would swap it out with the 104 jet that should let you rev past the 6000 mark.
