Thanks again for all the responses. I ran the engine yesterday on a quarter tank of fuel just to see if it would start. I cleaned the liner with a paper towel and the in line fuel filter with rubbing alcohol and put it back and added pure castor oil (around 18ml to about 50oz of fuel) and started it. It took longer to start but eventually did. I noticed that the high-speed needle didn't have much effect on the rpms when turning from 2 to almost 4 turns out. It did run rich with lots of oil from the exhaust and blue smoke. What also helped was it was cooler outside in the 50s, to avoid overheat issues. I plan to break it in per QwkSport2.5r suggestions.

Also, can you please explain why the break-in process is different for a ringed vs ringless engine?

Also how can running an ABC ringed engine too rich be bad for the engine? Just trying to understand the science behind it,
