good luck

I'm really new at this diesel stuff but you might start by trying to get all the carbon out of the glow plug holes. I reamed mine and was amazed at the crap in there.

It's not a switch.

I know it is just a poor label, and it really doesn't matter what you call things. But we are dealing with a precise, technical machine and labels do matter. OK, so your "stop lever" doesn't work either. Evidently your ignition "switch" doesn't work either. So, why don't you give us a little history on this problem and maybe we could help you solve the real reason you can't stop the engine. First though, in direct response to your question, that stop lever in some cases must be pushed "very hard". It is heavy sheet metal, and it won't break or bend from the hard push of your hand. I was surprised not too far back when a hose came loose on mine and I had to use the stop lever, as to how much pressure it took to kill the engine.

Still don't know.

Well, we still don't know the history of the problem. If it became a stopping problem recently, then I would check the vacuum connections under the hood, right in the area of the PB Booster. The lines for the ignition switch engine stop are a dark brown. Chances are that one has become dis-connected. That is a most common problem. If you can't "stop" the engine with the manual stop lever, then I think a rod adjustment is necessary. As I have not done. I can't say more, but I think a little experimenting on making this rod longer or shorter should give the desired results.

There's a brown vacuum line going to the shut off diaphragm almost directly below the stop lever between the back of the injection pump and the oil filter housing. Disconnect that brown line at the stop diaphragm and put a long piece of rubber hose in its place. Suck on that hose with the engine running. If the diaphragm is good a couple of strong sucks should shut it off. (be aware that if the diaphragm is ruptured, you could suck oil) If it does, run the hose out the cowling, shut the hood, problem solved. Just suck on the hose when you need to shut if off.
Report back with the results.
