Frank,

Could you explain how you can get better acceleration with the mixture leaned
out ?
I have always been under the impression that to get good acceleration the
mixture needs to be temporarily enriched.
Carbies that I worked on years ago had accelerator pumps to do this and when
they didnt work, the acceleration was definately hurt.
Of course if the mixture was excessively rich to start with...?

Thinking about getting one of those Euro boxes myself !!
