Should i just keep leaning it out until i get it as hot enough as it should be for break in?
NO, NO...do not lean out the HSN to get temps! Keep it slightly rich. What you should do is get yourself a heat gun. Some people use a hair dryer but a heat gun will heat up the engine better and faster. Heat the engine up to 180F before you start it. Then it will start up easier and the temp will be up there. Then drive it around a bit for 3 min. If it gets cold in the engine, bring it in and heat it up some more. Then set the piston at BDC (bottom dead center) and let it cool off. Then heat it up to 180F again before starting it back up. Temps are what you want. The engine needs to be hot to break in because the sleeve will expand around the piston that way. However, you do not want the engine lean during break in. You want it slightly on the rich side because it is tight between the piston and sleeve and you need the lubrication of the parts until it loosens up.
