Did you change the diaphragm? What else was replaced/done? Does it glow normally? How long do you glow? Old glowers have to glow for about 30 seconds.
The diaphragm cannot “enrich”: the mixture of a diesel engine is always lean. If you have a pneumatic governor and there is an air leak (such as a torn diaphragm), it can happen that the air valve is closed, so it is difficult to suck in air, while the control rod of the IP is too far in the full-load direction, that will result in smoke, but the engine will run.
During starting you pull the lever of the IP in the start position, then the start quantity of fuel is injected, that is even more than the normal maximum amount of fuel.
Non running of the engine usually means not enough diesel injected.

Thanks for the info,
so if i understand that correctly what you're saying is that it's simply impossible for a diesel to die from too much fuel? Are you 100% sure?
(Also another thought that just occured: I filled the IP with oil, and I remember reading somewhere that it somehow gets rid of excess oil. Does it do that by injecting it? That would make too much fuel very possible.)
I'm just asking this question specifically, because I don't want to go about changing the diaphragm for a lot of money just to have a non-running engine afterwards and another problem to fix

Well we seem to have a different definition of "good starter", here's what the brushes looked like vs. new ones:
and the inside AFTER cleaning it with sand paper:
after replacing them it turned a lot faster.
