i put a pump on my 1.6 td that was a spare...looks like its been played with....... i do have more power...less smoke but its not running right... i was wondering if any has any idea on base settings to go from... i dont really know the history on this pump but it does look to be in better condition than my old one and it doesnt leak lol
any suggestions would be appreciated...thank you

First of all, what's not right about how it's running??? The lack of smoke with good power tells me that the fuel screw setting is in the ball park..

i took it on a long drive today...added some ATF to the fuel....seems mouch better....no real smoke to speek of....best power its had yet...the cold start lever dosent seem to do any thing and it is hooked up lol ....it was a bit hard starting this morning and ran rough for awhile.....i think some thing was sticking in it and it broke loose..... ill try the timming advance later see if it willl work now or not....it may also be stuck in advance as well ... i have no idea on this pump

If it were hard to pump and pulling the advance did nothing I almost suspect you have it set too far advanced..
Do you know what you have it timed at by chance? If it is not smoking too badly and has the most power you've felt to date.. dont touch it
ITs running perfectly!

^^^ What he said.. I'm also thinking maybe your timing is a bit too advanced.. What was wrong with your old pump? Just leaking and poor performance? Any hard starting issues with it?

Run a few tanks through it and check the mileage before you go messing with it. It may be as good as it gets. Most of our machines run rough a bit when cold. Do they not? Not getting anything in the way of a response from the cold start lever makes me think to much advance as well. But if is only a bit hard to start, leave it alone and just put your foot 1/3 to 1/2 way down on the pedal to help it come up to speed once it does fire up. I run a second cable on the throttle lever as a means of keeping the throttle on all the time and it doubles as a high idle pull when cold.

oh it starts fine....sounds like a miss now... still pulls better that ever...must have picked up 20 kms an hr on the top end....and using alot less gears on hills....when i first tryed to start it ...when the pump was first put on...it ran like a turd in a washing machine...so i looked at my old pump...factorie settings on that one i think...all wired and the metal lock was on the max fuel bolt... i tryed to set my (new) pump up so it looked about the same... sure made it run better.. i think im in the ball park... but every thing was set way different on the new pump....all the anti tamper wires where cut ect...so i no other thing i could think of to go by...ill try pulling the advance back a bit tomorrow....do a check and make sure the cable isnt binding or something silly (silly sh!t always seems to catch me) il update here as i go...

You could try retarding the timing a bit.. Do you have a gauge to measure the timing with? If you do, I would suggest checking it prior to changing it and writing it down in case you want to go back exactly.
One thing I have learned (from messing with half a dozen or so pumps on different vehicles at different degrees of wear and tear) is..
ONLY CHANGE ONE SETTING AT A TIME
If you change two or more things at once you'll never know what did the effect you got.. and going back will be friggan HELL lol.

i was thinking last night.... with a bit of metal showing in my old pump i may hve a buggered injecter as well...hence the missing sound at an idle....so dug out a set lastnight and going to try them....i dont have a timing gauge/dial idecater so it is static timed...ill post my findings tonight...

Very,very good advice,as to test min 3 days or 50 km.

got a bit distraced...lol so i picked up a engine stethascope...retarded my timing slightly....now there,s a bit of blue on start-up....runs ok but still sounds like there,s a miss for awhile at idle.... had a listen to the injecters and one dose sound different to the others... so i think ill do the swap... crap!!! hope this will smooth the engine out a bit..
now,.... the timming advance.... i pill it and it doesnt seem to do any thing... it used to bring my rpm,s up now there semms to be no differance ... but it dose seem to be harder to start cold with it pulled...

well i left things alone... added ATF to my fuel see if that helps...it sure seemed to...
i did have a thought tho... i had put in a new motor mount before i did the pump...im thinking the stiffness of the new mount is making more engine noise travel through the car....making me think some things wrong when there isnt...it runs really well and its dam good on fuel (havent worked out mileage yet...but a tank last a long time)
i also chatted with a vw mech who said... if it has good pwer and not smoking badly ... not drinking fuel like mad... just leave it... so i think thats what im going to do .....for now....i just cant leave it be for to long .... they are to much fun to play with lol

What do you mean, you "static timed it"?
