So when I assemble these I always mark the ‘0’ mark and the notch on the IP sprocket with a silver paint pen to make it easy to spot. Well I marked the non-factory chip/notch in the sprocket. I’m so surprised I didn’t notice it before! Well I threw that sprocket in my scrap pile as it cost me many many hours :-(
I’m surprised that the engine was able to start that easy 180 off. The engine took about 4 seconds of crank time to start, and it actually idled smooth! I have never had one start this easy 180 off or idle that well.
Timing is now correct and it’s running like it should! :-)
Thanks ngoma!

Amazing, and a good call from ngoma to check it.
Funny how when you are "sure" it's not one thing, you'll try a million other less likely things first before coming back to what should have been obvious all along. I hate getting bitten by that situation. One time I had one go 180 off like this, but due in that case to a mistake on my part, and I was so sure I couldn't have timed it 180 out that I think I started looking at glow plugs, fuel prime, etc, even though it was an engine that had just been running no problem before I took the belts off it. Sounds like the same kind of outcome here. But in your case even more crazy because that trick sprocket would have made it look exactly right even when it wasn't, what a trip!
At least you know it must have great compression if it started and ran that well with the timing 180 off.
So what else is left on the swap now, must be pretty near done?
