257 cc Linhai Won't Start or Fire After Fuel Pump Replaced

Life got in the way of getting this thing going which I want so much soon. Thanks so much to everyone who has helped with that.

First I reset the intake valve gap then did a compression test since I could do that without removing a bunch of panels. 45 psi very low.I reset the exhaust valve gap to 0.20 mm and did a compression test.Compression was still only 45 psi.

What do I need to do next to get this thing going? I had fuel and spark but no compression. What else could be causing the low compression?Timing chain off by one tooth (this engine has two sets of marks, one on the timing chain sprocket and another on the engine main shaft and both are set right at the same time)?

Any ideas?
