Moose, why would he need to be putting Mystery oil in this engine if it rolls over? Just wondering, I use marvel for a number of things, I have just never used it to oil up an OS .46la?
Eagle, you have one of the best beginners engines ever made by OS. Do what Mike said in his last sentence and find someone that knows how to operate an engine and ask for some help.
If you can't do that then open the high speed needle about two turns out, take a straight pin and place it in the small hole in the carb and turn the screw on the side of the carb in or out until the hole is about half way open. That should get it running so you will be able to tune it. The carb is an air bleed type so it acts/adjusts a little back wards then most.
