Hi I run a peugeot 205 xs with twin 40s with about 115bhp but it's very rich on idle and fouls the plugs quickly but when driven it's fine, the emulsion tubes are F9 does that sound rite for the engine size?

the tubes wont be your problem
Any ideas what it could be?
idle jet size
Its finding a good Rolling Road operator that's familiar with jetting twin Webers etc in this day and age that can be a problem.
I do all my jetting on the road using a wideband AFR meter, car still goes on the rolling road to fine tune but generally i find fuelling spot on after road jetting and only use the rolling road to fine tune ignition settings and play with cam timing.
The car has been set up on the rolling road and drives great but does tend to soot up when idling, the idle jets are 54/F9
