The last couple of times I have gone to start the M3 from cold (left over night, very cold morn etc) it has struggled to maintain idle and if you put your foot on the accelerator to hold revs at just over 1k it seems to be over fuelling quite badly. A bit of white smoke and a strong smell of fuel. After about a minute of this it idles normally and is fine from there onward.....
Any ideas? Could the automatic choke not be operating properly? Any suggestions are greatly appreciated!
