Tonight I tested my injectors, since I figure calibrating a pump around bad injectors probably isn't wise.
Out of the 6 "professionally cleaned and tested" injectors, none of them were good. I have one new one on hand to compare them to, and really there is no comparison. The new one lets out a series of "chirps" as it lets of pressure, the old ones just dribble and squirt all over the place and wont hold pressure.
5 more new ones on the way! In the meantime I am going to try to clean these ones up but there's a chance they are just "done".
An action sequence.... not much to look at, sorry.
Also since I've decided to do my own heads, I dug out my Neway seat cutters but I was right in thinking they'd be a bit small for the 911 valves.
