I've shimmed the governor 4mm today, when we put it all back together and started it, it was idling at 3k rpm! The idle speed screw is not even touching the throttle lever, so we wound the max fuel screw right out until it idles at 1k rpm. However, it only seems marginally quicker than it was before, still peaking at around 18psi. Plus it barely smokes at all on boost, however it chucks out big clouds of the black stuff off boost. Any idea how I can wind the max fuel screw in for more power while keeping the idle speed low?

you put the throttle lever back on the wrong spline

gov mod only makes more fueling in the upper ranges possible, down low, power will be ths same

Its 100% on the correct spline, I marked it with a scribe. Although if I did fit it a spline out, would this make all the difference?

OK I'm willing to give moving it a spline a go... Should I turn it one spline clockwise? It had about quarter of a turn free play in it without the springs and lever on, so should I just turn it one spline clockwise or all the way to the other end of its freeplay?
I should also mention that my governor was missing the idle spring!! Is this normal for a UK spec GTD?

Next week I'm going to have the lever and springs off it again, I think it only has that quarter of a turn free play because its missing the idle spring on the governor. I'l take the lever off and mount it the quarter of a turn clockwise to the other end of the freeplay. According to my knowledge that should make the throttle lever actually sit against the idle adjust screw, and also allow me to wind the max fuel screw in (quite a lot) without raising the idle speed to excess speeds  ;D

this is the whole point of moving the throttle arm a couple splines..

I don't remember reading anything about moving the lever a couple of splines in the governor mod thread? And I read it about 3 times! Oh well, at least I know what I need to do to extract a silly amount of extra horses. And in other good news its still running well with the throttle lever where it is and the max fuel screw right out.

you can do the gov mod with stock fueling, but it works better if you move the pump arm a couple splines, and wind that fuel screw way in there. but mileage does suffer, because with all that added extra power, you will be using it!

I'm not worried about losing some MPGs, I'm running it on 60% veg oil at almost half the price of diesel! Once I've moved the throttle lever, and wound the max fuel screw in, should I expect a transformation in pulling power? At the minute it runs fine, smokes quite a bit off boost, makes a fine grey haze on boost, however I'm suffering with boost creep. It will peak at 18psi but if I keep on the go pedal it will creep to 20psi which makes me worry for the safety of the standard head gasket!

Right, that didn't go to plan! I took the throttle lever off, and turned the rod CW quarter of a turn until it wouldn't go anymore. Put it back on, it revved straight into the redline. Took it all off again, this time I turned the rod CCW quarter of a turn until it hit the resistance of the intermediate spring, then turned it CW one spline. It runs, idles at 900rpm, however there is a lot of throttle lever play before it actually speeds up. If I turn the max fuel screw in it raises the idle. I did try winding the idle adjust screw in all the way until it started to raise the idle, then I wound the max fuel screw in, raising the idle speed again. Hoping the idle would go back down, I wound the idle screw out, but nothing!

I really need help with this guys, its getting really old now!
Can anyone tell me how the flat screw drive sits on the top of the governor rod, in relationship to the two scribed marks on the 1st lever assembly? As I think this maybe the key to getting it set up correctly... I hope!

Thats what I've been doing, but I'm no sure which direction I should actually be going in. And when I'm being told to turn it CCW, is that the throttle lever, or the actual rod with the flat head screw drive on top? Its currently set with the two scribe marks on the lower throttle lever one spline CCW of the flat head drive on top of the rod, and it runs OK at this, however the idle adjust still does nothing, and the max fuel screw is wound right out.

I've just had an idea! Can someone show me a picture of how they're idle adjust screw and max fuel screws are set? Just so I can get a basic screw setting to go off, then adjust my governor rod spline by spline until it runs correctly.

I need the car running so I've put it all back to how it was before and its absolutely gutless! Its also got a fuel leak out from the max fuel screw, which I'm guessing is the O-ring at fault. We had to remove the screw from the pump when we had it open to remove the anti-tamper collar which was well on there! This is just getting worse and worse  >:( wish I'd never bothered taking it apart to do the governor mod now  ::)
