Technically, Yes. But there are things to keep in mind. Ambiant temps play a big part on what temp an engine will run. The oil will only cool an engine so much. If you richen an engine TOO much, to try to bring the temps down in excessive heat, you will run the engine too rich, causing extra stress on everything. If this doesn't make sense, intentionally flood your engine, then pull the pullstart.... Now imagine all that extra backpressure when the engine is turning 30,000 RPM + SOMETHING is going to give....

Get used to watching the way an engine runs when it is tuned right, Watch for good smoke coming from the exhaust, and LISTEN to what an engine sounds like when it is running right. Once you get used to those, it'll be much easier to notice if the engine isn't running right in different climates.
