Lately my 83.5 wc Westy has been been running a bit colder than normal. The normal spot for the temp needle is just to the left of the led while driving and lately it’s been about 2/3rds of the way to the LED.  I’ve been running rich lately too with diminished performance and lousy gas mileage around town (14mpg) but not sure if they are related.

Thanks,
Bryan
