Hi Dave,

Many thanks for your reply.

I have several emulsion blocks so I will do exactly as you suggest. Strangely enough, I always tighten all nuts, bolts and screws a little at a time, just like I would a cylinder head. I will (hopefully) be doing this job tomorrow. It is so strange how I have tried three carbs on this car and none, including the specialist rebuilt carb cured the problem, which is why I tried the pump.

When I rebuilt the petrol pump, I had to stretch the diaphragm slightly to make it fit. I then pumped paraffin through it as recommended in the service manual.

I will post my findings on the forum once I have taken the action you have recommended.

Thanks again Dave.

Kindest regards
