I'm still not quite there with this. very close though.
I'm going to try a smaller injector as my current one seems to spend a lot of time at minimum opening time but is still rich.
One question for the experienced guys on here... do you have a stream of small bubbles in the return pipe from the regulator?
I don't think these come from the pump as they only show after the regulator, looks like cavitation in the regulator. probably not an issue but I thought I'd check with you guys.
