600 Eddy tuning

It seems we all run, or have run Edelbrock Carbs.

I run a worked 1406 on a Bigblock 400....no problem.

From the sounds of it......I would Go Back to Initial Box Stock.....then you need to move the Accelerator Pump Rod DOWN to the bottom hole...Disconnect the Vacuum Advance hose, and plug the port....crank the engine up...then set the idle at 900rpm..let it warm up until it is at normal operating temp (whatever your stat is)......Make sure your electric choke setting has the choke blade FULL OPEN at this time..Start with the Driver Bank and run the idle mixture screw all the way IN to CLOSED...it should stumble and possibly even Die...thats ok....Recrank it...back THAT Idle Mixture Screw out 1 Full turn from CLOSED......then Repeat it for the Passenger Bank.

I believe that any fuel pressure OVER 7 psi WILL cause fuel to push past the needle/float assembly, momentarily filling the float bowls excessively, overruning the primary circuit during transition to secondary, and the addition of your pump shot was not in the bottom hole from the getgo.

If you have dual exhaust, What is your exhuast pipe diameter?

I run a NOT Touched, box stock 1406 on a Roller Cam 360, and it revs like a Monster.....my BB 400 runs a bit lean up top, but it runs great too.

Good Luck
