The smoke screw is the one on the back of the pump that sets the depth on the AFC diaphragm as far as I have known or been told.

yes the smoke screw is the one on the back of the pump. it is underneith a cover that has two bolts and one you have to use a chizzle to get out then replace the bolt or just leave the cover off.
