This is not what I would expect, but as you describe on the turbo is exactly what I would expect. I had a couple of off-line replies that indicated that Atkins only uses the nozzles in the rotor housings and that he just has the tip of the nozzles capped off. A picture on his website confirms this, so today I phoned him to confirm that he is still doing it this way. He is, however he said that the rubber caps can come off and any oil leaking past the internal check valve makes a heck of a mess, so he has changed the nozzles to a regular banjo bolt, since the orifice is located in the housings. (the secondary nozzles have the orifice built in). He is sending me a set of these. I modified the linkage from the oil metering pump arm (yeah, I know it's not actually a pump) to the throttle linkage to fit my system, and it operates the metering pump from 1/3 to 2/3 open. Dave says his is wired half open, with no problems, so mine should be better than fine. S.
