What's a good mixture for taxiing?

Post by mikeglaz »

I've been taxiing at around 50% and still this fouls up my spark plugs...

Its dependant upon where you are and conditions but for sure if your fouling you will want to stop leaning so much.

thanks,

For maximum effect, you want to lean as much as you can while having a smooth running engine. This would disallow you from advancing the throttle much, making up a safety measure as well in case you forgot to bring the mixture back full again when attempted to apply power for takeoff.

With default spark plugs, I've found the fouling simulation to be rather "worst case", almost as if a case of bad spark application, or mis-adjusted idle mixture (the full-rich setting at idle throttle).

Make sure to keep the RPMs up between 800 and 1000. That will keep the engine happy and also keep the batteries charging.

Have you changed to wire plugs?

Fine wire plugs will eliminate any fouling.

If instead you want to use massive plugs, you will need to keep your idle up closer to 1000rpm. This has more effect than leaning, as leaning on the ground except towards the absolute edge of the stall does little to nothing.

While many airplane engines can idle lower than 1000rpm with massive plugs without fouling, there is a fair amount that can't, and since we offer two types of plugs, we chose to model those airplanes in the fleets around the world that do require "anti fouling procedures" to be used.
