[urq] Rich (my car)

Is it likely that the hose on the WUR had been split for some time, the
mixture adjusted to compensate and now you have fixed the hose the car is
running rich?

Here's something else that is a bit rich....... me trying to answer your
mixture question when I've been asking eveyone else to help solve mine! (see
"suddenly lean" threads).
Never mind I hope it is something simple like I suggested above
As for urq owners being "rich" - they all start off that way....

All the best
