I followed the DoItYourSelf article for timing the IP and all I get is a steady stream from the drip tube even when I push the IP as near to the engine as possible.

That happens when the timing is retarded to the point that you run out of adjustment before reaching the desired start of delivery point. Not at all uncommon. You will need to remove the IP and re-index it to allow the necessary range of movement for adjustment.

To determine the actual start of delivery, rotate the crankshaft, not the IP.

Hi Tangofox,

Is there a DIY article or any information on re-indexing an IP?

Regards,
Andrew

The procedure is the same as when installing a new or replacement IP.
Set the crankshaft at desired start-of-delivery position, remove IP, align IP index marks, reinstall IP in center of adjustment range. Then adjust SOD.

You could probably get away with just pulling the IP out, rotating it (the entire pump, not the shaft only) in the retard direction, then reinstalling it. That will give you the needed range of movement in the "advance" direction.
