Mmmm... surely either the timing is 'spot on' OR it's 'advanced two notches'. In some guides I've read the advice is to advance the pump only as far as the adjustment slots allow, on mine
any advance means it won't run well, so it is timed purely with the timing pins.
It's easy to check the pump timing yourself. Take the crank position sensor out (it's to the right of the starter motor, behind the fuel filter, and is another component no longer needed with the Bosch conversion), push through a 12mm or 1/2" drill bit (or similar) and turn the crankshaft clockwise to find the timing hole in the crankshaft. You may need an assistant to achieve that with radiator in. Pull out the rubber cap in the top front of the timing belt cover and see if the hole in the injector pump pulley lines up with the hole behind it in the casting. If it doesn't then the timing is not spot on.
If you think the belt is slapping on the case then it isn't tensioned correctly and so it can't be timed correctly.
Here's a link to a guide on changing the timing belt...
