Re: Edelbrock 1403 runs rich after cleaning

Thanks guys.

I do have that 1486 kit akart, came with the truck when I bought it. It has a number of rods and springs so I just have to figure out the color code of the springs and I can try swapping in a lighter one.

Driving around today it looks like 35-50/- is the lean spot. Previous owner installed an LED meter on the dash that shows how rich it's running. Once I get below 18 vacuum, the meter starts to go up, so that tells me that the rods start to pull up then.

Also have to check the idle screws again, sounds a bit rich, but it could be the cam too.

On the upside though, its got some juice now! Which isn't bad since I move a lot of equipment and tractors.
