Means use a pipe tap.Explain for non mechanic please
Actually, ream the hole for a tapered finished. Look at this about 3/4 down the page for the right reamer. The hole is drilled accordingly.Means use a pipe tap.
That is not the droop screw. Droop screw or smoke cam is a nother lesson.I just learned about this techique from an old warhorse mech near FT Lewis,Wa yesterday.He stated the same things as Westech;dont' allow that droopscrew to rotate and or drop!Also,he and made task specific wrench for that job by grinding down a wrench to fit.Thanks for this post guys.Good info.
If your lucky when it breaks off in your hand the peice that is left falls into the pump and you take off the fdc and get it out of there.Will you know if the rod falls off inside if the screw is turned? How can one tell?
I think I just got lucky that mine was turned down like it was.WOOT! At least one of us had good luck.

5psi at 1600rpm and 10psi at 2600rpm under loadWell I think I found my problem. I hooked up my boost gauge today and took it for a spin, and going uphill I can only get about 6 lbs. of boost, max. From what I saw in another thread, I should be seeing 8.84 to 9.82 psi boost at 1600 rpms. Well at 1600 I'm closer to 4 lbs. or less.
Now...am I looking at just adjusting the droop screw, or is it a governor issue? I'm thinking droop, because I'm obviously getting fuel now, as i can see smoke while on hills.
I think the next step is to adjust the droop screw, and I think I'll back off the fuel until I get that corrected. but I'm going to wait until I get a response from someone in case I'm headed the wrong direction here.
BTW, its a quality gauge I used, Isspro, so it shouldn't be gauge error.

Was think going a little higher 6 or 7 and 11 or 12 and pre turbo 1200* all day long.5psi at 1600rpm and 10psi at 2600rpm under load
Set top rpm first then use droop screw to set low rpm.
There is a TM that covers all this can't remember #

Don't know what pump you have but if I had to guess you don't have droop screw but you do have smoke cam set at 33*. Needs to be less angle to increase boost. I will try and take some pics.Well I think I found my problem. I hooked up my boost gauge today and took it for a spin, and going uphill I can only get about 6 lbs. of boost, max.
