Lean Mixture

[Skoshi Tiger]

It seams to work well in the Spitfire IIa, following the manual settings for maximum range.

Air Speed 160 mph IAS, Mixture weak.

I found I was setting the govenor to about 2400RPM and then using the throtle to maintain about 2200- 2300rpm. I was trying to keep my manifold pressure as low as possible.

When I tried in a MK1a I found that my rpm was bouncing around a lot under 2400rpm and I found it difficult to maintain airspeed.

Cheers
