But in the UK, these pumps aren't as ten a penny as they are for you guys! It was very quick at 25psi, but thats about 1.7bar, I thought these engines could only handle around 1.2bar on a standard head gasket? It was running at 19psi before I was able to wind the max fuel screw in a bit further, and I expected it to raise the boost anyway due to the extra heat from the extra fuel...
there hardly cheap and easy to come by.. the only reason i have 10 pumps laying around, is because i scavenged them off my grandpas old, long gone projects..
usually its like oh, $100 bucks for a mediocre unit..
(i got a free car about a year ago, and it had a brand new pump and injectors just installed a few thousand miles before..

I stand corrected, ROR's had better luck at finding cheap pumps than I have.

i dont have that idle spring too...
i have on spring atached to the top,thought that that spring would control idle too as i have a good idle.
but also like adi i still have those splines problems as i have my lever sitting against the top body of the pump(doesent touch the idle screw) and cant add more fuel because of the idle that wont turn down more...

A lad in the UK on our mk2 forum has just had his governor out, and he's missing the idle spring too! Nice to know my car isn't the only one!

If you're talking about the one I'm thinking of it's for the cold start advance.

its the only one spring that ataches to the top.
and so why does the lacking idle spring affects the ability to lower the idle more by moving the shaft?
and why i have good idle?
so many whys lol...

that spring needs to be there to take up space. and for your cars governor to function at idle.
i imagine all you guys with no idle spring, are not even getting full throttle on the actual fuel collar.. that idle spring takes up space. and it was put there for a reason..

Or their governor is like a cummins, and has dispensed with 8 extra BS parts.

no, they dont have un-caged governors.. Adi states his governor is caged, just missing the idle spring..
they do have a spring in there, but its for the fast idle from the timing advance..

To get my idle down to something realistic I had to adjust the 2 little screws at the back for the advance. The left hand screw is all the way down, the right hand one all the way up. This is what quite a few people in the UK have had to do to get the idle to a realistic setting.

so,with no spring my idle is good.
if the spring takes up space in order to achieve full throttle why not to install something solid in order to have more travel?
i dont understand is why my idle is good,if they call it idle spring...
whitout knowing how the engine is idling and if somebody asked how it would do without that spring i would tell it would idle bad,like a drag truck...
i woudnt mind it would idle like a drag btw lol

The idle spring is probably there to reduce the little varied spots in the gov. operation at start up and idle. VW/Bousch probably quit putting them in as they realized it didn't make much if any difference in the real world. The pumps that I have had apart did not have an idle spring. They also had the yellow/red wax stuff on them to tell if someone tampered with it.
