Nah pumps rather different being the turbo one. Think I've got it sorted today. Have being playing with the pump for the last couple days and have worked out a few things as to which part affects what.
Got a bit concerned when it overheated idling for a while today but common sense prevailed and now the penny has dropped.
Inside this pump is kinda like wastegate diaphragm that you can rotate to alter the amount on enrichment unr boost and you can also adjust the preload on it which alters the ramp rate.
Got really lost between those two and the full load screw and had to start over yesterday, was rather Angus with myself for a bit.
