I just finished "Refreshing" my injection pump on my 350 Crawler/Loader and am having trouble with getting it started (cold/hot) and could use some advice.

The backstory: Typical Mouse Turds (EIC) governor weight ring disintegration was causing the typical issues. We tried for hours to line up both lines, but could never get the lines right or be able to slide the pin into the flywheel. SO I marked the Governor ring with a center punch directly across from the line on the distributor head and then pulled the injection pump. All came apart well and the motor stayed in it's current position and was never rotated at all.
After I finished replacing the EIC ring and all the o-rings and gaskets I slid the injection pump right back onto the driveshaft without any difficulty (Slid right on and engaged the tab on the driveshaft without any kind of resistance.)
TIP OF THE DAY: To keep the umbrella seals from rolling over during installation, I took a big zip tie (the bigger the better so it's wider) and turned it inside out (so that the zipper part would not catch (one side is smooth and the other side has the grooves)) and used it to squeeze the umbrella seal smaller onto the shaft. With a light lube, as you install the pump onto the shaft it will push the zip tie off the seal as the seal slides into the pilot tube. Then you undo (or cut) the zip tie and continue installing the pump onto the shaft. WORKED GREAT FOR ME!
After a lot of cranking and bleeding the injectors, we finally got fuel coming out of them all. But still, no start... weak battery. SO after charging the battery overnight we attempted again... Fuel to the injectors, great cranking speed, a little bit of whitish blue smoke but still no fire. Then while cranking we used small shots (very small) of either and instant fire... but it was like starting a jet engine... had to keep using a little laughing gas to keep it going until it built up enough speed and took off on it's own. Once it started hitting on it's own, it responded as it should to throttle and would idle fine, throttle up fine (smoke would go greyish then to a nice black smoke while rpms were increasing). Seemed to respond nice as it should. Although, no load would have alot more white smoke than I remember from prior to IP refresh.
Ran the motor for 5 or 6 minutes, then shut it down... Attempted to restart and no go... Had to gently use a little either to get it to fire... giving it a little shot every couple of seconds until it finally takes off. Its like it has a miss on one of the cylinders until it finally decides to go... I attribute this to still having air in one of the lines... This seems to be getting a little better with the more time I run the engine.
I've shut the motor off half a dozen times and attempted to restart with the same result... no go until we hit it with a lite shot of either until it gets going on it's own.
At this time I decide to attempt to track it back to the shop and out of the remote area where it's been sitting for the last few months. As I do this it started out fine, but quickly feels like its bogging down and losing power until I put the clutch in, then the rpms recover and I can go on again.
My questions are (Sorry for the long backstory) :
Is the hard starting related to the injection pump timing needing to be rotated towards or away from the block?
What does the different color of smoke indicate?
Thanks for any advice you can provide!
