I have almost a gallon on my novarossi b2000 bf.21 limited edition in my 8ight 2.0. What Im wanting to know is what is a good heat range to keep this engine running at ? I have read somewhere between 230-270. Is this correct ? I know not to tune to temp. and keep plenty of smoke coming from exhaust but kinda wanted a good estimate. I know different engines have different ranges. Any and all help will be used.
