P38 Diesel Injector Pump & Cam Top Dead Centre?

Right, got her running but she's very lumpy & idling at around 90rpm. So does that mean I need to slightly loosen the second row of bolts on the FIP and knock it forwards a touch. Guess the pump needs to be rotated anticlockwise a touch too. I'm still following Datateks plan as per timing but wondered if you guys knew which way I need to move the pump based on the description of performance?

I should add I matched the rotation of the pump up to the dirt outline around the flange where the pump had previously been.

No good guessing, what modulation figure do you have with the engine hot? I assume that you mean 900 rpm not 90?

yes, sorry. 900rpm not 90. My brother has the nanocom. I'll see if I can get a reading when he comes round.

However you adjust the pump angle, the final movement of adjustment must be toward the engine.

Cheers, I remembered that!
