Mopar Forums - 1971 M 300 (MH Chassis) TQ Adjustments

Hello again, Been awhile since ive been on.
I have been restoring a Winnebago D-20 Motorhome, it has the Dodge M-300 Chassis, 318-3 Engine, Loadflite 727 Auto, Spicer 70 Rear end ( I think Not positive yet)
I have removed the Carter BBD 2 Barrel and replaced it with a Stock 4 Barrel manifold and a TQ 850 CFM ( The carb # on it is 9077S), Electronic Dist.
I am stuck on exact carb setting in regards to the Step Up (Metering Rods) Screw adjustment.
Back around 1992-1996 I had documentation explaining the proper Screw adjustment procedures for setting the Step up (metering rods) In regards to running engine at a reasonable Speed with no load say 3-4K.
I have not been able to find the documentation and unfortunately I did not have a computer at that time so have no digital copy of the documentation.
When I rebuilt the carb I had removed the screw while doing a thorough cleaning of everything in the carb.
I have been going off of memory (which unfortunately is not as trustworthy as it was) I found that at about 3-4K RPM range (no Load) the engine seems to run the smoothest with to stutters-misses at about 4 Turns in (richer) from a Flush Screw head with top of Step up Piston.
I am curious if that sounds correct to anyone or better yet if someone has the ability to point me in the correct direction to regain the documentation on the adjustment.
Thanks
