Hi,

Black Soot eliminated . As you know I just replaced the fuel injectors on my 1982 500SL Euro 107 and have now found the complete elimination of black soot coming out of the exhaust upon cold start when the auto choke is on .

For the last few years I have had this thick black soot at cold start, that goes away as soon as the auto choke shuts off hiowever new injectors have fixed this .

Can anyone please explain .
