Hello there-

My 560 sec emits an odor like rotten eggs out the exhaust at idle. It's pretty pronounced. Too rich or too lean? Which way does one turn the mixture screw to lean or richen the mixture??

I replaced some injectors recently and the car runs way better but now has this smell. I suppose someone reset the mixture to compensate for dirty injectors but now I don't know which way to turn the screw to lean it out. Help!!
