OK update. Well I've worked out what should be happening and when. Glow plug is working and glow heater is working as I tested them - many times. I'm using Byron's fuel so that can't be an issue. The CEN site states that 99% of starting probs are with plugs/heaters but not here. So possibly flooded. Well did as Craig from Oz suggested and 'drained' any excess fuel via plug hole and tried again. I cannot get it to even cough or pretend it's catching. Is it really important to have a buddy blip the throttle for you as you try to pull start - especially a new engine?
As was suggested, use the trim adjustment to open the throttle for you. You don't need much, watch the carb end while you adjust it and stop when you see it move just a bit (1mm). If you get your buddy to open with the trigger I reckon it will be too much and after a pull or two you will have flooded the engine. Keep pulling, short and quick, a new cold engine may take a few tries.
When you drained the excess fuel, you should have flipped it upside and pulled the starter several times, then put the plug back in reasonably tight, right? My first mistake was to not tighten very much but it really needs to be sealed at least. You can tell if its not by quirting a bit of wd40 at the plug and looking at the plug while you pull the cord. If you see bubbles or movement then the plug isn't tight enough IMO. My truck wouldn't start at all until I had it tight, dispite what the manual says about loosing the damn plug to make it easier. Don't forget it will need to be primed again.
Craig.
