1966 sunbeam alpine - stock set up
my car runs great for the most part, but it runs better still when I pull the choke out just a bit. Without the additional choke, it might bog down when hitting the throttle - going up a hill. It then seems to run flawlessly with the additional choke.
Having to pull the choke out suggested to me that I was running a little lean. So I thought I should back the jet off / down a little. Before doing so, I pulled the plugs today and all four were uniformly dark with carbon. This suggests to me that I have been running rich- the blackened plugs.
Am I running rich or lean?
Is this a problem that can be cured by doing something other than raising or lowering the jets?
Thanks all
