Assuming that the engine is teh stock ones then a quick google search turned up the following info.
2 1/2 out on the high needle and 3 out on the low needle.
Follow THIS guide for tuning your engine.
If you can't see fuel flow through the fuel lines to the carb then you probably have an airleak somewhere. Make sure theres no airleaks in the fuel tank and replace all the fuel tubing.

Id switch out glow plugs for a fresh one if you havent already and if it still does the same thing then I believe that is a sign the LSN is to rich if I'm not mistaken, Id try leaning the LSN out a bit and see if that helps.

Did you prime it? How about the plug, did you replace that?

Have you verified that the glow plug ignitor is fully charged? Also, I see that you have the air cleaner off of it. Look down the carb and make sure that you have the idle screw turned so that you can see about a 1mm slot showing down in the carb.
I understand stock settings are HSN level - LSN level . . .
HSN is about a turn down . . . (12 hours!)
LSN is also down - unsure by how far but a easily noticible amount . . .
This is where we ended up last night after a few hours of tuning!!!WOT runs ok - slight lean bog from start - low yet stable idle - runs at 150F - too scared to increase the size of the idle gap in fear of changing the LS tune - if I lean the HSN I am moving even further away from stock tune (indiciating something is not right) and of course I am chasing myself with the HS - LS effect.
