Hello guys!
sad update: today the engine gave up and it won't start, all i see is some dark smoke and it failed to start after trying all day. I found the cold start lever, it didn't help and i fixed the decompression lever properly today and it became easy to turn by hand. I checked and there are no air leaks in the system.As for the injector it's less than two months old so in my opinion it's probably not the origin of the problem. I guess now it came down to the fuel pump and honestly i don't know where to begin with it.
 As always looking forward to hearing your opinions my friends.

 Hello and thanks for your reply, i can't seem to find the cold start button on my engine, the throttle is fully open when i crank start it and the valves are properly adjusted recently. However, i'm not sure if the fuel pump is properly adjusted or not and i have no idea how to do it but from what i can see the engine runs normally but the difficult starting problem remains. as i said before when i turn it manually and reach the proper momentum it doesn't start after releasing the decompression lever, it requires a few turns after the release and sometimes it doesnt start even with that. By the way the air filter is new. I did all i could to narrow my choices and now in my opinion it comes down to the fuel pump. how can i verify if it is the source of the issues and if it is how can i adjust it? thanks in advance

Hello again guys! so i inspected the decompression lever and there was indeed some adjustment issues which i fixed. The engine became a bit easier to hand turn but not the same as before so the problem is kind of always there. The other problem i discovered is that it starts after a few attempts and by a few attempts i mean it starts when you're very close to dislocating your shoulder because you turned it too many times. When i turn it by hand to a reasonable speed and close decompression lever it usually doesn't start until the 5th or 6th attempt of doing the same procedure even when i continue turning a bit (with compression) even though i sometime see some smoke . This means i'm getting a power stroke but it's not powerful enough to start the engine which leads me to believe that the problem is with the fuel pump. When the engine starts, its behaviour is completely normal so my opinion is the effort done by hand is no longer sufficient for the pump to provide enough fuel to start te engine but the engine power is enough to properly turn the fuel pump. Since there isnt that many parts in this engine my guess is the fuel pump. what do you think my friends?
by the way the fuel injector is new.

Thank you for your answers, i always disconnect the water pump ( belt driven) before cranking the engine since it makes the rotation much easier. However, i'm facing this problem without coupling the engine to anything. I'm going to take a closer look tomorrow and i'll keep you informed.
Thanks again.

Thank you all for the tips i appreciate it. I will start with the adjustment of the decompression lever and valves then i will verify the oil quality and carbon deposits. Eventually if nothing solves the problem i will have to disassemble the engine and verify thr rings and all the bearings.
By the way the engine is coupled to a water pump
I'll keep you posted , have a great day!

Hello!
i have a Lister ST1 diesel that was working properly but all of

point out the problem knowing that it did not overheat at any point and it's well cleaned and lubricated.
Thanks in advance
