View Full Version : Temperature change?

The weather here in Northern Illinois has been in the 70's low 80's mostly low humidity. The temp this weekend is likely to be in the 90's high humidity. I have not run in this hot weather before. What most likely will I have to do to the engine settings, if anything?
I have a Nitro Quake with the Torq 21 engine it has hi and low needles Thanks

It may sound odd, but it's been my experience that if all other weather factors remain the same, you may have to lean the fuel mixture slightly. When the air is hot, it's very thin and lacking the density of cooler air. When this happens, there's less oxygen to burn the fuel, so you have to reduce the amount of fuel going into the engine. You might think that hotter ambient temps would require more fuel to keep the engine cooler, but it's not that simple.
