I've got a 2 barrel mercarb on my 4.3 lx. Since I've owned it I've always had trouble starting it cold. Today I'm looking at the carburetor and noticed the electric choke is set to the leanest position. Why would this be? Maybe the previous owner adjusted it incorrectly? Maybe it came from the factory this way? Except for basic maintenance work this motor appears to be completely unmolested and in beautiful condition. No oil leaks of any kind, all paint in great condition and no rust spots anywhere. So, why would this electric choke be adjusted so lean. I've enclosed a pic of the setting on the choke as I found it. I'd say it needs to be adjusted more rich (counter clockwise) . Could this contribute to my hard cold start issue? Am I missing something here?
