To start with I know what the problem is, I need a new IP that’s calibrated but I don’t have $1500 for a new one right now so I’m hoping I can tweak the current one I have a bit.
A few details: timing is set @8 degrees @2000rpm pulse method, throttle goes to wot so the cable is good, new standyne G code injectors, new racor fuel filter, electric fuel pump (mite be a problem as I don’t have a way to check pressure under load), engine is a rebuilt 94 idit, ip is from my old 87 6.9 which was replaced at some point in its life, turned up 2 flats.
Now a while ago I had to pull some of the pump apart to change a leaking throttle shaft seal which required all the governor linkages to be removed, I did carefully measure the guide stud and put it back as close as I could and same with the face cam for the light load advance. I have good power when the cold timing advance is on but it sounds like a Powerstroke and the timing at idle is 11 degrees with it on, I don’t want to start burning glowplug tips off by advancing base timing to much.
So what I have noticed is the light load advance retards the timing, if I floor it without having enough rpm it looses all the diesel clack, doesn’t even puff grey or black and craws up slowly in speed. Did I grossly miss adjust the light load advance? Is the light load advance doing anything a 1/2-wot? Is the governor way out? I can’t get this to puff anything unless I almost stall it at take off or lug it at 1000 rpm in 3rd, wot at 1500 rpm in 4 doesn’t even haze which is why I’m hoping that I can do some adjustments to get this thing acting better till I can get a new ip.
So besides a new pump is there anything I can try with this older pump to make it run better? I think I’m going to up the fuel a bit more and maybe play with the lite load advance cam a bit but any suggestions would be very helpful. Also fuel mileage is down right disgusting at 10m/g.
