"Standoff" is the term used to describe the condition of a cloud of
gasses hanging outside the inlet of the carburetors. We most often see
it on SU and Weber-carbureted cars on cool, foggy mornings. It is
usually attributed to sonic resonance in exhaust systems, where the wave
bounces back and hits the exhaust valve at the moment of overlap.
I had a TR4 on the chassis dyno recently that experienced a higher
degree of this than I have seen before.
Has anyone else experienced this and / or dealt with it?
