flat piece? the plate or gov arm?

 

the flat thing

the flat thing is the gov arm... it shouldn't be hitting foot tho. correct me if i'm wrong, but the foot sits at the top of the afc... yes it hangs down a little but the arm shouldn't reach up there... http://www.pdrdiesel.com/oldsite/TechLeverAdj.htm

 

im pretty sure thats he thing thats hitting and making it feel like i have no bottom end this weekend ill have to take a look at that and see

 

bottom end should be at the bottom of the plate, well away from the top of the afc housing foot. i know you know what your doing, so maybe just try checking the low end problems again... such as making sure the foot isn't getting below the plate, and star wheel adjustment. the only other thing to check would be your boost numbers at the low end. maybe something will click as your checking these things over.

 

the gov arm should contact the afc arm ... the gov arm will hit the afc arm before it hits the fuel plate.

hook your afc up to some shop air and see if its moveing. mod it if you have not already and make sure the afc spring is not binding up.

 

it seems really tight and i dont have the spring that tight

 

if your trying to move it by hand your its gonna feel tight till you break the seal on the diaphram. put some air to it and see how it moves

 

how much?
