Edelbrock Carb specialists please !
 

I have a Buick V6 231 3.8l motor in my car. It had a computer assisted carb set up on it. When I bought the car I ripped it all off and went with a Edelbrock intake and 1406 carb (600cfm), I replaced the distributor with a none computerized HEI distributor and other then that it's all stock.

The car has always run really rich (duh) and about ever 6 months I would remove the plugs and things would be good.

I had never intended for this motor to stay in this long so I never assumed I would have these issues.

When I bought the carb, it was the smallest one Edelbrock had and some of the other ones that were a little smaller were out of my budget range.

Now, the help I need is understanding and figuring out which Metering rod, jet and step up springs to allow it to run the leanest mixture so the car will run right.

The carb came with a .098" primary jet, .075"x0.47 metering rod, and a yellow 4" step up spring

Hope that helps

Thanks for the help...........

Since metering rods are easier to change then jets, I'd start there. Larger rods allow less fuel through the primary jet, so go up in size.
