Star wheel is now turned smoke screw is a bit more in and fuel plate is all the way forward. Thanks alot for the help guys

 

Welcome

 

Just to make sure I am not missing something the starwheel = smoke screw right? Sounded like everyone was talking about two different things, if so please feel me in.

 

The star wheel is on the inside of the pumb andsmoke screw is on the back under a little cover held on by 2 bolts.

 

-So the smoke screw = more or less smoke, more if tightened?
-Then what does the star wheel do? I turned my starwheel down a bit once I popped my fuel plate in for less smoke and it seemed to work.

 

Mopar1973Man's Dodge Cummins Articles - P7100 Injection pump - AFC (Starwheel) look on here it should fill you in

 

Fuel plate (under AFC)= max fueling (how much fuel is injected overall)
Starwheel (inside AFC)= fuel in relation to boost
"Smoke Screw" (back of AFC)= zero boost fuel

The smoke screw affects how much fuel is injected at zero boost. The starwheel either puts tension or releases pressure on a spring. Boost pushes against that spring, thus increasing fueling when boost is higher. If you tighten or loosen the starwheel, you are either increasing or releasing pressure on the spring.

Think about it this way. If you take some of the springs tension away, you make it easier for boost to push against it, increasing fueling. Turning the starwheel towards the engine takes tension off of the spring, making it fuel harder in relation to boost, while turning it away from the engine puts tension on the spring, making it fuel less in relation to boost.

Hope thats clear enough

 

just gutt the afc housing and you dont have to worry about any of the screws

 

That helps, thanks! Here is a good PDF I found with lots of info.
