• Hey I just got a new IP from thedieselstore.com about a month ago... $450 shipped with core seemed great, and it has been.
  But its gotten to where the idle is hangin. It'll carry itself @ 25mph in 5th. A quick rev won't knock it down, but if I pull the cold start and push it back on it'll fall back down.
  Any ideas? I'm gonna call them on Tuesday as I think I have a warranty

• That is what I would do if it has only been a month.  Let them suggest the fix rather than start turning screws and such and then have them deny a return later.

• Yeah every screw on the damn thing has yellow jiffy lube paint on it

• The better to see if you were fooling with them, Grandma
  
  They think they rebuilt it correctly and set it accordingly.  Hence the paint, break the paint, break the warranty. 
  
  Call and talk to them or get stuck with a dysfunctional pump for 450 bucks.  Not a good ider now is it?

• Hahahah yeah Ima give them a jingle on Tuesday. Meanwhile Ima check about this 91 NA that just landed @ the boneyard; Ima need it either way, specially if they want this one back for repair

• Sounds like you have a late MK2 pump with the idle-up lever that's connected to the cold-start lever. You'll see it on the back of the pump. There is an extra shaft with a spring on it that connected to a second lever on the throttle lever. My old pump used to do that, especially when it was cold outside. And, the only solution was to pull the cold start lever a few times to get it to drop. I later found a massive air leak on one of the return lines, so I can't rule that out as part of the problem. Eventually, I pulled the pump and swapped in an early Rabbit pump I had rebuilt. No problems since.
  
  I'd say spray some penetrating oil all over those levers. It may be that the new seal is making the throttle lever bind a bit.

• yay this was the kind of info i was looking for; infact i was on my way out (as soon as i research hydro heads on mech blocks) to see if there was something related to the cold start area that could be causing this.. i recently had all my oil blow out my dipstick tube when my PCV clogged up (it's an experiment i've got going; trying to calm the smoke down with steel wool in the PCV hose before it exits from under the car) and it got oil all over the pump and every other thing, so that whole area just got an entire can of starting fluid.
  it likely needs just that.
  i'll report back

• well i wasn't able to find anything of real value, except there's some kind of adjustable long stick that goes down to the cold start that looks like it might be a possible solution, but again it's got yellow on it too.. shucks i'ma wait till tues and see what they say
  
  hey does turnin the fuel screw in till it smokes (like it appears everyone is doin) turn the gas mileage down much? i'd like to smoke when i accel now

  All that smoke is diesel that was burnt.

  Well, just how much do you enjoy smokin' tailgaters?  It comes at a cost and with diesel still floating over 4 bucks a gallon I just hit the emergency flasher rather than the pedal.  
  
  To Answer your question in short, YES.  It does depend on where you set it so it seems.  You may get it so that you really have to floor it to make it smoke and then you would not loose much economy if you tender foot it.  I laugh at the honking diesel pickups that bellow black all the way up the same hills I don't.  If I ever see one in the station filling up they all tell me they get good mileage on diesel.  Like 20 -22 is good?  Maybe for them but when they ask about my mileage I tell them they don't want to know, when they ask again and say they are interested and I show them the record of 44-50 they about cry.  So smoke comes out and dollars go with it in my way of thinking.  But then I am considered a little weird.
  
  Smoke'm if you got em.

  hahahah ok.. i'll stick with my non-smoke gas mileage then.
  i figured if i was breakin the yellow jiffy lube seals i'd go for smoke too.

  thats going to make your idle hang even worse.. turning the fuel screw up..
• #12 by Giles@PerformanceDiesel on 01 Jun, 2011 07:02
• try unscrewing the residual fuel screw, the one that the throttle lever rests against.

  wow i feel honored you'd try to help!
  
  i assume you mean this one:
  
  
  i turned that down after thedieselstore.com (where i bought the pump) told me to; you can even see were it's been cranked out..
  
  that didn't even lower the idle with the problem solved..? now it does nothing as i turn it until it hits the point it used to rest at; then the idle comes up as you turn the throttle..? i thought for sure i'd get a lower idle by crankin that out a bit.
  
  well anyway, the problem is that the cold start creeps up when the engine revs up.. so you have to push the cold start back down, but the cold start handle cable doesn't have enough ass to do that .. so i zip-tied the cold start down for now you can actually see the ziptie in the photo (runnin up to the fuel line that my dumb ass took the rubber insulators off of and lost_
  
  Edit: well I have found that the little knob goin to the cold start is related. It's still wonky. Now I've got these screws all wound every which way and I either have high idle, or teeth chatterin battery light blinkin low idle. Shucks.
• #14 by ORCoaster on 01 Jun, 2011 20:40
• Can you get it back down to the teeth chattering stage and then bump the timing up a little and get it to smooth out?  Oh and I would love to have that fitting under the OUT banjo of yours.  1 drill+tap+fitting = internal pressure gauge.
