So I believe I'm catching on; (thanks guys!). In my pic here, am I correct that the entirety of the device shown is the INJECTOR and the red arrows are pointing to the "back plate" that, if removed, I'd see/expose the governor? Someone posted a video with a clear plastic plate in place of the metal one and that's the governor spinning around at the bottom...? And in this video, it sounds similar to mine a few days ago, after I had it parked th sideways on a hill with the tank around and 1/8th full. I think I got air in there, but, bled it out - maybe not 100% - but it ran decently or well. I will go and loosen the fuel line on the right at the injector and just keep cranking for a bit - see if I can see fuel spit out. But it was weird, (as I mentioned earlier), I removed the entire short fuel line from the injector body and nothing come up. I cranked a good 10-15 seconds. Wondering if there may be dirt in the injector ... Maybe I post a video if trying to bleed again doesn't do it.it is passed my bed time but watching Barcelona-Real Madrid Now. but, quickly here, Governor is internal to the injector, you cannot see it from outside. if you take the back plat eof the injector then you can see if.it is directly attache to a can shaft that rotates. the lobes on the cam shaft reciprocate two small piston and with right valving it suck fuel and then injects it causing a lot of pressure and very little flow (fuel flow). if you have a air trapped there in the line it keeps compresses the air without pumping fuel. just remember air is compressible but not liquid fuel. The injector need to be bled as close as you can to actual injector. It would take a while for the fuel to fill and empty pipe as voulume of flow is low. I am not sure if yiu completely bled the air out. I had to do it several times in the last 20 years due to running out of diesel and I know the voulume of fuel is very small and is fuel pump is pulsating and sending very little fuel next to the injector anytime I bled air out of my 1700.
