Carburetor Calibration Tuning Kit for Edelbrock CFM 1400 1404 1405 1406 1407 1408 1409 1411 WPA 1487 Carter AFB Carburetor Jets Rods Springs Metering Jets Sizes 95 98 101

All the parts you need to properly tune your carb

the jets are the wrong thread--the rods are not marked and are the wrong size and the springs are useless don't get ripped off=this is junk

Jet threads were perfect and metering rods also worked -didn't use vacuum springs or metering rod hold springs. one star less- You do need to measure jet and metering rods because they are not stamp marked.

Got this kit to lean out my edelbrock 600 that was previously tuned for a chevy 355 with a fair sized cam. My stock 283 runs a little rich with this carb. I'll use the parts in this kit to get the mix as close to a stock calibration as it can get. We'll see how it goes....

Parts would not fit and threads were bad

Wish I could spec what parts sizes are in the kit

Springs are not colored

Jets are actually the wrong thread size for a 1406 these are m8 when edelbrock is 5/16 24
