I finally got my 1050 dom running perfect this summer,but now that winter is here and the air has changed it seems to be running pig rich(according to my afr guage).is that a coincidence or am I having carb or tune problems?this a street mostly car but does get to the strip at every chance.

well you should have the exact opposite problem now that the air is better. learn to give the motor what it wants and don't rely totally on your afr. if it still sounds and runs good don't worry about it. thats my opinion.
What Tony said... in the cool weather the carb tends
to lean out due to the temps... so for yours to
be going fat is strange or your getting a bogus AFR
reading... as said.. what does the engine tell you
and the plugs

I agree should be the opposite of what it is.its hard to get a reading on the plugs with in town driving.i guess ill just keep drivin it and see if the plugs foul out.it seems to run fine and I don't smell gas in the exaust.just seems weird that my cruise went from low 14,s to low twelves,assuming that this guage and sensor is working.plus it wants to run on a couple of licks every time I shut it off.

Running on is hell on a motor. Maybe shut it down in gear to stop it as a bandaid.
it don't sound good that's for sure.its not like its diesiling it just cough,s thru the card a couple of licks like theres to much gas in the cylenders.

Run on is a sign of being fat on the idle.. assuming
that the engine isnt still decelling.. but if your
at idle for a few seconds then its fat

Not saying this "is" the case but I have found when something changes for no apparent reason like your describing I tend to look for a partially blocked air bleed first. Then dig into the carb making sure the power valve (s) and or block off's are tight. Gaskets can and will cause the same issues your describing. Metering block gaskets can cross feed circuits and power valve gaskets can take a set causing torque loss adding unwanted fuel to the power enrichment circuit. If you need new gaskets just ask around here on the board who has the best

First thing I would try is pull the carb, blast the heck out of the air bleeds venturies... with a big can of carb cleaner, re-install and see if that helps. I have seen where "these bleeds" get a light coat of build up dried fuel additive and a slight restriction that richens it up.
I am not causing global warming, I am just trying to hold off a impending Ice Age!

Bleeds.............idle and hi speed.............what r they. 
I`d be curious to see if/how your idling on the t-slots and as Greg stated, the bleeds can/will get dirty and throw the idle off.
