I'm not going to say you're wrong, but I will say that I respectfully disagree with most everyone here (in some way... but that is how life goes, huh?).
190-195 may be good, but I wouldn't know because I am not running the engine in. Only then would I know the weather conditions, the engine performance and other intanglibles that cannot be measured quantitatively. Therefore, I tend to disagree when someone says (as you have) ... it should be around 205-210....
Don't get me wrong, it is very good advice, and that is a range during the first or second tank that I find is perfect when breaking in my engines. However, if the day is more humid... I would say also that 215 degrees would be acceptable because of the weather conditions.
Don't take offense I used your remark as an example, but it was the one closest to the reply button
After that being said, I want to give this as well... You should really watch how the engines behaves on this next upcoming run, super dave. After having the problem of a leaking tank, the engine tuning may become a bit more important as you find how well it really runs with a proper fuel system. It should run differently and make sure no radical performance or temp changes occur in the next run. Since you have not had any major problems yet, I think you should be okay as it seems you are going along quite well.
Ahhhh.... breaking in a motor, the part of rc that is like art class for the scientist.
