There are two schools of thought on these engines. You may have signed up for the wrong "class."
TT engines are a bit different. They have to be run stupid rich. Filthy, Donald Trump, Bill Gates, rich. And the SMALL (so-called) idle needle is the critical one. I would start out at LEAST 4 turns on each. I think mine was about 5.5 on the second engine before the temperature behaved. Don't turn the large needle more than 4 out or it will FALL out.
Think of the small needle as a direct link to temperature. If the engine is purring like a kitten and running real nice, you are overheating it and you WILL burn it up.
Do a search. There is a massive amount of info on this engine and the similar pain TT50.
For the first 3 to 6 tanks, run it so rich that it practically wants to shut off. Then start leaning. Most folks end up around 3 and 3 (or lower on the large needle) after initial break-in. Of course there are a LOT of variables so watch those temps!!!
Do NOT use castor oil - never mind what the manual says.
