Hey everyone, new to this forum, I’ve got a ‘94 f350 with a non turbo 7.3 IDI, 127,000km on it. She shakes more than I think is normal at idle and my tach shows 100RPM at startup, MAYBE 300rpm during high idle (slight bouncing of the needle as well) when it’s cold and it seems to lag some when I press the accelerator to come up to speed, but once I’m driving it has a normal response. What do you guys think? I haven’t adjusted anything, but apparently the previous owner “advanced the timing a little bit”. Not sure if the photo helps, but maybe someone will notice an adjustment needed.
