Went out this morning for a drive. It was 2C (35F). I got a couple of pops of the old popoff valve, so I gave the mixture control unit a 1/8 clockwise turn and it's back to smooth running.
This will probably do me until I put the car away in about 5 wks.
Come next spring I can gradually lean it as we get back to warmer temps.
Since I have no O2 sensor, DME, or other electronics to do this for me, what could be easier?
